A new damage evolution criterion for the coupled Eulerian-Lagrangian approach: Application to three-dimensional numerical simulation of segmented chip formation mechanisms in orthogonal cutting

A damage evolution law is proposed to consider the frictional behavior within an Eulerian material after full damage as a Lagrangian material, where the mesh explicitly describes the newly born interface interactions. This approach is prominent for simulating severe plastic deformation (SPD) processes during which material separation can occur. Among these, orthogonal cutting represents the simplest process for comparison with the simulation...
