两种弹塑性算法的比较

Comparison Between Two Algorithms for Elastoplasticity

分析了弹塑性一致切线模量算法与径向返回算法，发现一致切线模量算法并不如有关文献报道的那样，比径向返回算法有快得多的收敛速度，两个算例表明了这一点。这使对一致切线模量算法有比较全面的看法。

In this paper, the consistent tangent modulus method is compared with the radial return mapping algorithm and it is found that the former is not more numerical efficient than the latter, not as some paper reported. Two numerical examples are given.
