FETI-BASED HOMOGENIZATION OF FIBROUS COMPOSITES WITH INTERFACIAL DEBONDING

Abstract eng:
In this contribution, we present an efficient FETI-based algorithm for homogenization of fibrous composite materials with imperfect interfaces. The proposed formulation allows for a seamless combination of the initially-rigid connection, monotone traction-separation relations due to Kruis and Bittnar (2008) and a contact conditions (Dost´ l et al., 2007). The performance of the developed algorithm is illustrated on two representative numerical examples.
