Corrugation problem in the car trunk sealing strip edges is analyzed with the highly non-linear finite element analysis software (MARC). The structure and material is optimized.
It is also presented a finite element analytical model suitable for non-linear analysis of HFB flexural members.
采用有限元方法，建立适于冷弯截面受弯构件性能分析的非线性有限元分析模型。
