A Study on Preparation of Failure Parameters for Ductile Polymers
A study on preparation method of failure parameters for ductile polymers is presented using experimental results of high-speed tensile test for Polycarbonate and simulation results based on Semi-Analytical Model for Polymers (SAMP) constitutive model [1] in LS-DYNA®. In addition, a comparative review of two widely used failure models, namely, total formulation and incremental formulation [2, 3], is carried out using Charpy impact test simulations where the failure parameters are prepared using the proposed method. It is found that the incremental formulation is excellent in predicting the experimentally observed behavior of notched Charpy impact test and non-notched Charpy impact test.
