摘要
本文建立了一种光塑性迭代混合法,可用于平面塑性问题的全场应力分析。该方法的基本公式在弹性区自然退化为拉普拉斯方程,对原始实验数据的需求量小,受不稳定的实验数据的影响也较小,因而具有良好的精度。
A method for elastoplastic stress analysis based on photoplas-ticity and finite difference iteration was proposed for full field analysis, in which only a small number of data input were required. A theoretical equation derived by the author could degenerate into Laplace's equation in the elastic field. Fewer test data were required in. the calculation and moreover, the accuracy was higher.
