TL;DR: In this article, the performance of lithium-ion battery modules is investigated by conducting tensile tests of the module components, constrained compression tests of dry module representative volume element (RVE) specimens, and a constrained punch test of a small-scale dry module specimen.

TL;DR: In this article, a modified random sequential adsorption algorithm was employed to generate the complex geometry of a random fiber composite and the effect of the interaction between two over-crossing fibers on the overall elastic properties of the composite was evaluated using the finite element method for continuum micro-mechanical analysis.

TL;DR: In this article, a cylindrical representative volume element (RVE) containing an initially spheroidal void and subjected to some axisymmetric loading is considered, where the major stress applied is the axial one so that the strain is mainly vertical.

TL;DR: In this article, a micromechanics-based approach to the strength properties of composite materials with a Drucker-Prager matrix in the situation of non-associated plasticity is described.
Abstract: The present paper describes a micromechanics-based approach to the strength properties of composite materials with a Drucker–Prager matrix in the situation of non-associated plasticity. The concept of limit stress states for such materials is first extended to the context of homogenization. It is shown that the macroscopic limit stress states can theoretically be obtained from the solution to a sequence of viscoplastic problems stated on the representative elementary volume. The strategy of resolution implements a non-linear homogenization technique based on the modified secant method. This procedure is applied to the determination of the macroscopic strength properties and plastic flow rule of materials reinforced by rigid inclusions, as well as for porous media. The role of the matrix dilatancy coefficient is in particular discussed in both cases. Finally, finite element solutions are derived for a porous medium and compared to the micromechanical predictions.

TL;DR: In this article, a quantitative study of the size of representative volume element (RVE) of random matrix-inclusion composites based on a scale-dependent homogenization method is presented.
Abstract: This paper presents a quantitative study of the size of representative volume element (RVE) of random matrix-inclusion composites based on a scale-dependent homogenization method. In particular, mesoscale bounds defined under essential or natural boundary conditions are computed for several nonlinear elastic, planar composites, in which the matrix and inclusions differ not only in their material parameters but also in their strain energy function representations. Various combinations of matrix and inclusion phases described by either neo-Hookean or Ogden function are examined, and these are compared to those of linear elastic types.
