摘　　要：以热推弯管变形分析为实例，在实验基础上综合考虑温度效应、应变速率、变形程度、应力状态与含碳量等因素对碳钢材料力学性能的影响，兼顾准确性和计算简单性建立了碳钢弯管成形过程材料本构方程。给出了一种建立材料塑性本构方程的实验分析方法，为复杂条件下钢结构分析奠定了基础。An experimentalanalytic method which is used to establish the material plastic constitutive equation is given.In this method,based on the experiments,the analysis on the forming process of pushing and bending heated tubes is taken for example,the factors such as heated temperature,strain velocity,deforming degree, stress state and carbonous amount ect.,which could influence the materials mechanical properties,are synthetically considered.Attentions to accuracy and simplicity on calculation are also given.
