DEFORMATION LOCALIZATION FOR PLANE STRAIN TENSION OF POLYMERS

A kind of BPA eight chain molecular chain network model based on strain softting glassy polymers is introduced into the Updating Lagrange finite element formulation A driving stress finite element method of elastic plastic large deformation suitable for the deformation localization analysis is proposed Using this method, the plastic flow localizing propagation for the plane strain tension of initial isotropic polymers is numerically simulated Adaptation of the BPA model to crystal...
