Note (General): We proposed the new model which combined not only the elastic-plastic model used from the former as a material model but the rubber elasticity model. It is a model who is predominant the rubber elasticity in the region where the strain is low, and shifts from the rubber elasticity to the elasto-plasticity in the high extension strain. This material model was included in LS-DYNA, and the stress-strain curve of the actual PET film was reproduced. It is expected that these results lead the improvement of the accuracy of the FEM analysis such as the PET films and PET bottles.
