Application of Plastics CAE: Focusing on Sumitomo Chemical Co., Ltd. Impact Analysis Plastics Technical Center Masaaki TSUTSUBUCHI Tomoo HIROTA Yasuhito NIWA Tai SHIMASAKI To review recent topics on impact analysis in the field of plastics, this report outlines the application trends and analysis techniques followed by an explanation of the characteristic physical properties of resins which may be the key points for their practical application. First we introduce how we predict yield stress under a wide range of tem- peratures and strain rates. Second, for the elastic-plastic model, we explain that it may be appropriate to consider dependence of yield stress on stress state and volume increase due to craze generation. Finally, we show how fracture behavior depends on temperature and strain rate. 9) CAE Computer Aided Engineering Fig. 1 a 1) 1980Dr. Jason R. Lemon Fig. 1 bCAE 2000CAO Computer Aided Op
