| Abstract(E) | This paper describes the development of analysis method for predicting a crack or a fracture in polymer parts. In recent years, demands to reduce the number of prototypes and vehicle scale tests by utilizing CAE analysis are increasing. Material model which considers the dependencies on stress-triaxiality and strain rate, was employed. Material tests with proposed test pieces were conducted to evaluate its validity and determine material model parameters for CAE analysis. Crash simulation with a component of vehicle parts was conducted to validate CAE modeling and analysis method. Crack initiation phenomena in polymer parts was validated with proposed analysis method. |
