摘要

推荐了热翻边时孔扩展的应力-应变分析关系式。从理论上证实了各向异性材料的粘塑性状态。在平面应力状态图中采用了修剪方程和屈服条件。得到了工作材料连续性的关系式。给出了计算结果。

Viscous-plastic hole extension when flanging a heated sheet

Correlations for stress-strain analysis for the cases of the hole extension in flanging when heated are recommended. The state of visco-plasticity of an anisotropic material, is approved in principle. Trim equations and yield conditions are used in the plane stress state sketch. Correlations for the work material continuity are obtained. The results of calculations are given.
