| 摘 要： | It has been shown that the traditional small deformation plasticity can be transplanted to the finite deformation plasticity by using the logarithmic strain measure only. In this way, the mathematical problem of how to find the derivative of a tensor function arises. In this paper, a general method for finding the derivative of a tensor function is proposed. Several metal forging examples are given.During the calculation, the mesh regeneration is not even invoked.
