Abstract A thermomechanically consistent Eulerian plasticity model with work hardening is adopted for studying the residual mechanical state resulting from loading at elevated temperatures. The isotropic plasticity model includes the standard effect of thermal softening as well as specific modeling of thermal recovery. The model parameters and functions were calibrated to data for an austenitic stainless steel 316L. The model is applied in two numerical examples: a case of uniaxial tension and a circular disk that is exposed to a temperature load. The influence of thermal recovery is examined for each example by comparing the response of the complete model with thermal recovery to that when thermal recovery is omitted. The results of the second example indicate the importance of modeling thermal recovery for accurate prediction of residual stresses for problems dealing with melting and solidification.

热回收对熔化和凝固过程中残余力学状态预测的影响

摘要 采用具有加工硬化的热机械一致欧拉塑性模型来研究高温加载导致的残余力学状态。各向同性塑性模型包括热软化的标准效应以及热恢复的特定模型。模型参数和函数根据奥氏体不锈钢 316L 的数据进行校准。该模型应用于两个数值示例：单轴拉伸的情况和承受温度载荷的圆盘。通过比较带有热回收的完整模型的响应与省略热回收时的响应，检查了每个示例的热回收的影响。
