abstract: Instability phenomena occurring in the microstructure of composite materials are investigated. To this aim, a
complete description of the mechanical behavior of bi-material interfaces in composite materials requires the
definition of both a cohesive law involving damage for the debonding stage, and a contact model during the
closure of the interface. Both formulations are herein presented and implemented in the FE code FEAP.
Numerical examples showing the transition from a snap-back instability to a stable mechanical response are
presented.
