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. date: 2005 date_type: published publisher: Curran Associates pagerange: 5928-5933 refereed: TRUE isbn: 978-1-61782-063-2 book_title: Proceedings of the 11th International Conference on Fracture 2005 (ICF11) citation: Carpinteri, Alberto and Paggi, Marco and Zavarise, Giorgio Theoretical and numerical investigation on internal instability phenomena in composite materials.
