The frictional contact of the composite fabric’s shaping

Abstract : In this paper, we are interested in the forming of a composite part by deep-drawing and laying-up processes. We present a new bi-component finite element model for the simulation of these processes. The augmented Lagrangian approach is adopted to treat the frictional contact between the composite part and the tools. This augmented Lagrangian treatment is well established for the numerical treatment of metal forming processes [12]. It is based on a new way of writing Coulomb’s friction law. Some numerical results are given to validate the proposed numerical method.
