Investigations on engineering structures show that residual stresses in combination with external loads can cause failure in loads that are less than the design threshold. Due to the applicability of austenitic steel in important industries (such as oil pipelines), accurate measurement of residual stress in this material is very important. Indentation is a new method for estimating residual stress. In this paper, by performing a large number of finite element simulations, the accuracy of residual stress measurements in austenitic stainless steels using indentation was studied by performing a large number of finite element simulations. Three different models (Suresh's, Wang's and Lee and Kwon's model) were investigated and it was found that the Lee and Kwon's model has a more accurate prediction of residual stress values in austenitic steels.

Based on these numerical simulations and by studying how the residual stress measurement error of Lee and Kwon's model changes according the stress ratio, a method is suggested to correct this error and calculate the real amount of non-equibiaxial residual stresses in austenitic steels. The procedure is significantly reducing the error of residual stress measurement (from about 50% to less than 10%) and has been verified by conducting experimental test on a sample made from austenitic steel.

对工程结构的研究表明，残余应力与外部载荷相结合会导致小于设计阈值的载荷失效。由于奥氏体钢在重要行业（例如输油管道）中的适用性，因此准确测量该材料中的残余应力非常重要。压痕是一种估计残余应力的新方法。在本文中，通过执行大量的有限元模拟，通过执行大量的有限元模拟，研究了使用压痕法测量奥氏体不锈钢中残余应力的准确性。研究了三种不同的模型（Suresh，Wang和Lee and Kwon的模型），发现Lee和Kwon'

在这些数值模拟的基础上，通过研究Lee和Kwon模型的残余应力测量误差如何根据应力比变化，提出了一种校正该误差并计算奥氏体钢中非等轴残余应力的实际数量的方法。该程序显着降低了残余应力测量的误差（从约50％降至小于10％），并且已通过对奥氏体钢制成的样品进行实验测试得到了验证。
