9361070萨克斯本研究旨在发展一种新的粘塑性本构模型,该模型利用内变量来模拟包辛格效应。它将考虑速率和温度的依赖关系、大应变运动学和合适的旋转应力速率。该模型将使用现有的拉格朗日有限元计算机代码实现,并将通过将模拟预测与几种常见实验和制造配置的实验结果进行比较来验证。***
英文摘要
9361070 Sachs This research is to develop a new viscoplastic constitutive model which utilizes internal variables in order to model the Bauschinger effect. It will account for rate and temperature dependence, large strain kinematics and a suitable corotational stress rate. The model will be implemented using an existing Lagrangian finite element computer code and will be verified by comparing simulation predictions with experimental results for several common experimental and manufacturing configurations. ***
