I am developing a Lagrangian 2D model. I made parts for both work piece and cutting tool with dedicated material proprieties for each one. I defined plastic and damage model. Then to get Temperature profile I assigned specific heat, Conductivity and thermal expansion to both material model. I also defined the sacrificial layer with the feature of deleting elements.Although I got results from normal dynamic simulation such as stress and strain, in (Dynamic Temp, Dis) I got too much of mesh distortion. Could anyone help me to fix it ?
