Interfacial damage nucleation and evolution in reinforced elastomers is modeled using a three-dimensional updated Lagrangian finite element formulation based on the perturbed Petrov-Galerkin method for the treatment of nearly incompressible behavior. The progressive failure of the particle-matrix interface is modeled by a cohesive law accounting for mode mixity. The meso-scale is characterized by a unit cell, which contains particles dispersed in a homogenized blend. A new, fully implicit and efficient finite element formulation, including consistent linearization, is presented. The proposed finite element model is capable of predicting the non-homogeneous meso-fields and damage nucleation and propagation along the particle-matrix interface. Simple deformations involving an idealized solid rocket propellant are considered to demonstrate the algorithm. (c) 2006 Elsevier B.V. All rights reserved.
