A Variational Approach to Homogenization of Composites with Debonding Interfaces
Original language description
Failure in fiber-reinforced composites is often initiated at the fiber-matrix interface; the load-induced debonding phenomenon is therefore of crucial importance when assessing the overall behavior of composite structures. Numerical modeling of interfacial behavior within the framework of displacement-based (primal) Finite Element method is usually based on interfacial elements. To overcome the well-known problems related with the primal formulation, in the current contribution we investigate an applicability of duality-based solvers to the homogenization of composites with imperfect interfacial bonding. The basic theoretical framework is provided by the first-order strain-based homogenization theories and the Finite Element Tearing and Interconnecting(FETI) method. A generic interfacial traction-separation law is approximated via a sequence of reasonably defined linear problems.
