Abstract

In this work we present a micromechanical model for two-phaseductile/brittle laminates that captures the macroscopic behavior, as well asthe underlying micro-mechanisms of deformation and failure, in particularthe synergy between the inelastic deformation mechanisms of crazing andshear yielding. The finite element implementation of our model considers athree-dimensional representative volume element (RVE), and incorporatescontinuum-based physics-inspired descriptions of shear yielding and crazing,along with failure criteria for the ductile and brittle layers. Theinterface between the ductile and brittle layers is assumed to be perfectlybonded. The model successfully explains the volume fraction effect on themicro and macromechanics of ductile/brittle microlaminates subjected touniaxial tension.
