In this work we present a micromechanical model for two-phase
ductile/brittle laminates that captures the macroscopic behavior, as well as
the underlying micro-mechanisms of deformation and failure, in particular
the synergy between the inelastic deformation mechanisms of crazing and
shear yielding. The finite element implementation of our model considers a
three-dimensional representative volume element (RVE), and incorporates
continuum-based physics-inspired descriptions of shear yielding and crazing,
along with failure criteria for the ductile and brittle layers. The
interface between the ductile and brittle layers is assumed to be perfectly
bonded. The model successfully explains the volume fraction effect on the
micro and macromechanics of ductile/brittle microlaminates subjected to
uniaxial tension.
