A numerical approach for crack-induced damage in tungsten carbide cutting tools during machining

Cracking wear is one of the major phenomena that affect the lifetime of cutting tools. Delamination may be the last stage and the inevitable outcome of the propagation of cracks that may initiate anywhere in the coating or at the coating/substrate interface. To explore this phenomenon, the standard finite element analysis (FEA) FEM analysis was performed, in a first step, to calculate the energy necessary for crack deflection at the interface...
