Diamond metallic laminates (DML) have been demonstrated to exhibit an improved toughening mechanism by modifying the crack driving force with alternate hard and ductile layers. A systematic investigation was set up to understand the behavior of these multilayer system with/without metallic interlayers through analytical,  experimental Insitu 3PB, cantilever bending along with Finite element modelling (FEM) were included.
