几种各向同性屈服准则的比较分析

Comparison and Analysis of Several Plastic Yield Criteria

  • 摘要: 为对新屈服准则进行深入研究,本文比较并分析了H.Tresca和Von.Mises屈服准则,M-C和D-P屈服准则,双剪和三剪屈服准则的发展及应用,重点介绍了以上不同类型屈服准则的基础理论,并对比了其几何意义、适用性以及实验验证结果;最后指出,对于今后屈服准则的研究可考虑从完善传统屈服准则屈服面不封闭以及重视相应的实验验证两方面来深入进行.

     

    Abstract: In this paper, the development and application criteria of H. Tresca and Von. Mises yield, M-C and D-P yield and twin-shear and triple-shear yield were first comprehensively compared and analyzed with focuses on their basic theories, geometric meanings, applicability and verification. The new yield criteria were put forward to improve the imperforation of the yield surface of the traditional yield criteria and the applicability of new criteria was further experimentally validated.
