A Model of Metal Cutting Processes Based on an Eulerian- Lagrangian Finite Element Technique

本研究的目标是开发一种先进的金属加工模型。这项研究将建立在采用拉格朗日弹塑性动力有限元模型的成功初步研究的基础上。这项工作将结合先前的工作和欧拉方法来处理金属弯曲剪切区中的过度网格变形。这项研究将产生一个耦合的拉格朗日-欧拉模型，该模型将包括温度效应和应变率材料特性。材料特性数据将以实验方式生成，以在模型中使用。将进行加工试验以验证模型的有效性。

The goal of this research is to develop an advanced model of metal machining. This research will build on successful preliminary research employing a Lagrangian elastic-plastic dynamic finite element-based model. this work will couple the prior work with an Eulerian approach to handle the excessive grid distortion in the metal curring shear zone. This research will result in a coupled Lagrangian-Eulerian model which will include temperature effect and strain-rate material properties. Material property data will be generated experimentally for use in the model. Machining tests will be performed to validate the model.
