TFA-based Homogenization for Composites Subjected to Coupled Damage-friction Effects

The present paper deals with the formulation of a new homogenization procedure for the determination of the overall response of composites subjected to nonlinear phenomena due to the development and growth of cracks. An interface model accounting for damage, unilateral contact and friction is described. Then, a homogenization technique, based on the Transformation Field Analysis, is developed. A numerical algorithm for the time integration of the evolutive problem is formulated within a predictor- corrector procedure for solving the time step nonlinear problem. A numerical application is presented to assess the effectiveness of the proposed approach.
