    © 2019 Elsevier Ltd In consideration of the dependence of resin properties on the degree of cure (DOC), a method of decoupled two-scale analysis of unidirectional fiber reinforced plastics (FRP) is proposed to simulate the curing process subjected to the temperature history that may cause residual stress and deformation at the macro-scale. Within the framework of computational homogenization, a series of numerical material tests (NMTs) are conducted on the periodic microstructure (unit cell), which is composed of fibers and resin, for various cure states to characterize the macroscopic material behavior and its dependency on DOC. The resin's material behavior at the micro-scale is assumed to be viscoelastic based on the generalized Maxwell model whose properties depend on DOC, and be accompanied with thermal expansion/contraction and cure shrinkage. On the assumption that the macroscopic mechanical behavior of FRP can be represented by the orthotropic version of the model employed for the resin, its DOC-dependent macroscopic viscoelastic properties as well as the macroscopic coefficient of thermal expansions (CTEs) and coefficient of cure shrinkages (CCSs) are identified from the relaxation curves obtained by the NMT results. In addition to this key ingredient, the noteworthy contribution in this study is the introduction of a new configuration of the rheology elements to formulate the macroscopic CTEs and CCSs in both the equilibrium and non-equilibrium parts of the generalized Maxwell model. After some verification analyses for these DOC-dependent material properties, we present a macroscopic analysis followed by a localization analysis for estimating the macro- and microscopic residual deformations and stresses of a laminate subject to curing to exemplify the successful decoupling for two-scale computational homogenization.

    © 2020, Emerald Publishing Limited. Purpose: This study aims to propose a novel viscoelastic–viscoplastic combined constitutive model for glassy amorphous polymers within the framework of thermodynamics at finite strain that is capable of capturing their rate-dependent inelastic mechanical behavior in wide ranges of deformation rate and amount. Design/methodology/approach: The rheology model whose viscoelastic and viscoplastic elements are connected in series is set in accordance with the multi-mechanism theory. Then, the constitutive functions are formulated on the basis of the multiplicative decomposition of the deformation gradient implicated by the rheology model within the framework of thermodynamics. Dynamic mechanical analysis (DMA) and loading/unloading/no-load tests for polycarbonate (PC) are conducted to identify the material parameters and demonstrate the capability of the proposed model. Findings: The performance was validated in comparison with the series of the test results with different rates and amounts of deformation before unloading together. It has been confirmed that the proposed model can accommodate various material behaviors empirically observed, such as rate-dependent elasticity, elastic hysteresis, strain softening, orientation hardening and strain recovery. Originality/value: This paper presents a novel rheological constitutive model in which the viscoelastic element connected in series with the viscoplastic one exclusively represents the elastic behavior, and each material response is formulated according to the multiplicatively decomposed deformation gradients. In particular, the yield strength followed by the isotropic hardening reflects the relaxation characteristics in the viscoelastic constitutive functions so that the glass transition temperature could be variant within the wide range of deformation rate. Consequently, the model enables us to properly represent the loading process up to large deformation regime followed by unloading and no-load processes.

    &lt;p&gt;A data-driven approach is developed for micro-macro coupled multiscale analysis of hyperelastic composite materials. The offline process in this approach is to make a database that stores the microscopic stress distributions in response to various patterns of macroscopic deformation gradients. This can be done by carrying out an adequate number of numerical material tests on a periodic microstructures, or equivalently, a unit cell and followed by the proper orthogonal decomposition (POD) to extract the principal components of the data along with the corresponding basis vectors. In order to realize FE&lt;sup&gt;2&lt;/sup&gt;-type two-scale analysis in the online process, we interpolate each of the coefficients with the radial basis functions as a function of a macroscopic deformation gradient and make the resulting continuous function gently varying by means of the L2-regularization followed by the cross-validation and Bayesian optimization techniques. Each of the functions thus obtained is referred to as &quot;data-driven function&quot; of the microscopic stress distribution and can be used to obtain the macroscopic stress by the averaging process in the homogenization method. A representative numerical example is presented to validate the proposed data-driven FE&lt;sup&gt;2&lt;/sup&gt; analyses in comparison with high-fidelity direct FE&lt;sup&gt;2&lt;/sup&gt;.&lt;/p&gt;

    We propose a new method of multi-scale analysis for plate-like devices such as a flat plate cell of solid oxide fuel cell (SOFC), which is classified into a composite plate composed of in-plane periodic structures. To characterize the macroscopic nonlinear mechanical behavior of the in-plane periodic structure, the method of numerical plate testing is employed. Since the obtained relationships between macroscopic generalized strains and stress cannot be represented by an equivalent homogeneous plate with a single material, we introduce a surrogate model composed of homogeneous layers that is expected to exhibit the same macroscopic responses. After the material parameters of these layers are identified, the macroscopic analysis becomes possible by use of a laminated structure with continuum solid shell elements available in a general-purpose finite element program. Representative numerical examples are presented to demonstrate the capability of the proposed multi-scale analysis method.

    The treatments of heterogeneities and periodic boundary conditions are explored to properly perform isogeometric analysis (IGA) based on NURBS basis functions in solving homogenization problems for heterogeneous media with omni-directional periodicity and composite plates with in-plane periodicity. Because the treatment of the combination of different materials in IGA models is not trivial especially for periodicity constraints, the first priority is to clearly specify points at issue in the numerical modeling, or equivalently mesh generation, for IG homogenization analysis (IGHA). The most awkward, but important issue is how to generate patches for NURBS representation of the geometry of a rectangular parallelepiped unit cell to realize appropriate deformations in consideration of the convex-hull property of IGA. The issue arises from the introduction of overlapped control points located at angular points in the heterogeneous unit cell, which must satisfy multiple point constraint (MPC) conditions associated with periodic boundary conditions (PBCs). Although two measures may be conceivable, we suggest the use of multiple patches along with double MPC that imposes PBCs and the continuity conditions between different patches simultaneously. Several numerical examples of numerical material and plate tests are presented to demonstrate the validity of the proposed strategy of IG modeling for IGHA.

    Purpose - The purpose of this paper is to propose a set of constitutive functions for dried bodies for accurate prediction of the entire deformation process of ceramic products during firing and to present relevant methods for determining their coefficients from a series of respective thermo-mechanical analysis (TMA) tests.
    Design/methodology/approach - The function forms of the sintering-induced strain rate, viscoplastic multiplier and elastic modulus are formulated in order with reference to empirical data of relative densities. Separate TMA tests are conducted to identify their coefficients, while a stairway thermal cycle test is carried out to identify the parameters in the densification rate. Then, various finite element analyses (FEA) are performed for accuracy confirmation.
    Findings - The performances of the present constitutive functions along with the identified material parameters were validated in comparison with the relevant test results. It has then been confirmed that these functions enable us to some extent to accurately estimate the non-mechanical and mechanical deformations of dried bodies during firing. Also, by performing FEA of an actual sanitary ware product, the applicability and capability of the proposed set of constitutive functions could be demonstrated.
    Practical implications - The present methodology with the proposed constitutive functions is a simple, but reliable and practical approach for simulating the deformation process of arbitrary ceramic products subjected to firing and applicable for practical applications in various engineering fields.
    Originality/value - The constitutive functions of the viscoplastic multiplier and elastic modulus, which enable us to properly characterize the mechanical behavior of dried bodies subjected to firing, are originally formulated in analogy with that of the sintering-induced strain.

    地震履歴により免震ゴムは損傷を受け,揺れの減衰能力が低下する.一方,ゴム材料は潜在的に自己治癒能力を有しており,その能力は熱を与えることで引き出すことができる.当研究はビルの廃熱などを利用してゴムの自己治癒能力を積極的に引き出す仕組みを新たに構築することを目的とする.また,その一環として,自己治癒能力を利用したゴムの損傷回復が構造物の免震機構に与える効果を定量的に評価するために,損傷回復効果を再現可能な数理モデルを構築し,実験を通してその妥当性を評価する.

    In this study, we proposed a method of thermo-mechanical coupled two-scale analysis (space-time multi-scale analysis) taken into account microscopic unsteadiness of deformation and temperature fields in order to simulate thermo-mechanical coupled behaviors of fiber-reinforced thermoplastics (FRTP). As a result, we illustrated that the fluctuation temperature is related to the microscopic unsteadiness of the microscopic temperature field and reflected in the macroscopic unsteadiness along with the unit-cell size.

    In order to resolve the problem of deterioration of underground structures after construction due to swelling of rock mass we have developed a new multiscale multi-physics rock mechanics approach. We carried out laboratory swelling tests of montmorillonite and formulated a thermodynamics model for the swelling behavior. We also formulated a numerical analysis model based on the modified Cam-Clay model that can predict deteriorating strength and stiffness of rock mass along with a rigorous return-mapping algorism. Then we developed a multiscale multi-physics analysis model for swelling rock mass by Incorporating the thermodynamics swelling model into the Cam-Clay type model. A series of analyses of a tunnel within a swelling rock mass predicted displacement and stress distribution around the tunnel in good agreement with measured data. We conclude therefore the validity and effectiveness of this proposed multiscale multi-physics rock mechanics theoretical model.

    Based on the co-rotational formulation to deal with large displacements and rotations of a solid, we propose a method of multi-stage failure simulation of brittle materials and structures involving dynamic frictional-contact behavior. In order to simulate dynamic behavior of the structure, we adopted mid-point algorithm along with energy-momentum method. Also, we employed the penalty method to represent the brittle fracture due to gluing/separation of the elements, and the augmented Lagrange method to consider the frictional contact effects. Verification tests were conducted for the formulation with a simple structure subjected to the large displacements and rotations. Also, some simple numerical examples were presented to demonstrate the capability of the proposed method to simulate the multi-stage failure process.
