“…Usually, the equivalent stresses should be consistent with the yield criterion. [ 22 ] It is presumed that the mechanical behavior of Ti6Al4V can be described by J 2 criterion, [ 23,24 ] and then σ eq and ε eq can been expressed as σ eq = s i j : s i j , ε eq = 2 3 ε i j : ε i j where s i j ( s i j = σ i j σ normalm ) is stress partial tensor, and ε i j is strain tensor.…”

“…The element type for the Eulerian medium, workpiece, and void is an eight-node thermo-mechanical coupled linear Eulerian brick element (EC3D8RT). A size of 5 microns in the cutting zone and an orientation of 90 • with respect to the cutting direction of the Eulerian parts are established based on [14] outcomes. The tool elements are eight-node linear thermo-mechanical coupled brick elements (C3D8RT).…”

“…Therefore, it is understood that the model does not accurately simulate the experimental chip formation mechanism. Recently, Xu et al [14] developed a 3D model based on a newly developed plastic behavior law capable of predicting both segmented chip formation and the existence of a material-side flow. The damage laws in all models introduced have been based on the JC law for the initiation and energy criteria for evolution.…”
