Study of impact analysis for plastic parts with rib structure - Part 1 benchmark problem of crush analysis and results of experiment

摘要

With the spread of CAE at designing stage of automobile, the numerical simulation technique to evaluate impact behavior is demanded also for plastic parts. However, due to its strong non-linearity of plastic material, accumulations of know-how for numerical analysis is still far from sufficient. The benchmark problem settled to develop computer simulation technique for crush analysis for ribbed plate made by rubber toughened polypropylene, and test results are reported.
