本文用连续介质损伤力学(CDM)理论,在引入真实损伤变量的概念之后,建立了包括板料n、R值的理论成形曲线(FLC),并与实验结果进行了比较。
In this paper, by using the theory of continuum damage mechanics (CDM), after introducing the concept of real damage variables, theoretical shape curves (FLC) including sheet n, R values are established and compared with the experimental results.
