Abstract. The mechanisms of the deformation and fracture of coated materials with varying coating thickness and coating-substrate interfacial curvature parameters are investigated. The boundary-value problem in the plane strain formulation is solved numerically, using the finite-difference method. In the calculations, an explicit account is taken of experimental and model microstructures with irregular and sinusoidal coating-substrate interface geometries, respectively. The stress concentration in the near-interface region is shown to increase with decrease in the coating thickness and increase in the sinusoidal interface amplitude. This dependence is nonlinear in character.

“…Due to a hierarchical composite structure, these studies need to cover multiple scale levels. The established modern paradigm for such studies is the multilevel approach for describing structurally inhomogeneous materials [1][2][3][4]. Multilevel models of plastic deformation and damage are advantageous over the classical approach adopted in mechanics in a way that they allow one to observe stress concentration phenomenon leading to microcrack emergence at early deformation stages.…”

“…Thus, in order to adequately describe damage process, one needs to acquire the data on stress-strain state history under severe plastic deformation conditions. To achieve this goal, numerical simulations employing different software are widely used [2,3,[9][10][11][12]. Simulation results allow one to obtain sufficient data for further computations.…”

Abstract. A three-dimensional model for deformation of metal matrix composite with aluminum matrix and silicon carbide reinforcement particles is developed. The model accounts for an internal structure of the composite, as well as rheology of its constituents. The model is further used in numerical simulations in order to study the evolution of stress-strain state parameters in a randomly-chosen composite microstructure fragment under uniaxial tension and compression loading on micro-and macroscale. The parameters include the stress stiffness coefficient, the Lode-Nadai coefficient and equivalent (von Mises) strain. It is found that local deformation regions and internal tensile stress concentration regions appear in the material of composite matrix. Adhering to a phenomenological damage theory, a damage development is computed in the matrix metal. We present damage fields and damage distributions for uniaxial tension and compression.

is an open access repository that collects the work of Arts et Métiers ParisTech researchers and makes it freely available over the web where possible. Metz, France AbstractIn this paper, the analytical solution of the multi -step homogenization problem for multi -rank composites with generalized periodicity made of elastic materials is presented. The proposed homogenization scheme may be combined with computational homogenization for solving more complex microstructures. Three numerical examples are presented, concerning locally periodic stratified materials, matrices with wavy layers and wavy fiber reinforced composites.
