Sensitivity analysis of composite forming process parameters using numerical hybrid discrete approach

Abstract : The aim of this study is to investigate the influence of some important parameters in composite forming using a hybrid discrete hypoelastic computational model developed for simulation of the deformation behaviour of fibres materials. This model is based on elementary cell of shell or membrane type reinforced by nonlinear connectors. Moreover, it can follow the rotation of the fiber during the forming process. The constitutive model has been implemented in a commercial FE code (Abaqus Explicit) via a user material subroutine VUMAT. It has been shown that the forming simulation is affected by the process parameters like the binder force, the coefficient of friction and forming speed on the shear angle distribution.
