| Abstract: | To cut development time and cost of design process, demand for CAE is increasing. To develop computer simulation technique for crush analysis, JSAE set up a working group to select benchmark problems and perform simulation trials among members. Several tensile and compression tests are carried out to evaluate the effect of strain rate and temperature on mechanical properties of plastic material. Then, crush tests of a specimen (plate with ribs) made by rubber toughened polypropylene are carried out to prepare benchmark data. Through trials of computer simulation and comparison with benchmark data, several key parameters of crush simulation are found. |
