本文提出了一种基于温度的弹塑性区域尺寸确定方法。开发了描述塑性区传播的一维热问题的数学模型，使得能够在该角色中使用非绝热温度测量。使用数值生成的温度数据对模型进行的验证表明，所提出的方法可以对弹塑性边界产生准确且稳健的估计。实验应用表明该方法是有效的，并且弹塑性边界的估计与有限元分析获得的结果非常吻合。
This paper presents a temperature-based method for the determination of the size of elastoplastic zones. A mathematical model describing the one-dimensional thermal problem of the propagation of a plastic zone is developed enabling the use of nonadiabatic temperature measurements in this role. Validation of the model with numerically generated temperature data has shown the proposed method to yield both accurate and robust estimates for the elastoplastic boundary. An experimental application revealed the method to be efficacious and the estimates for the elastoplastic boundary to agree well with those obtained by finite element analysis.
