WebbIt can be concluded that in order to have a high theoretical cleavage strength, a materials must have high E and surface energy and small distance between atomic planes. This strength is a function of the cohesive forces between the atoms. Experimental values lie between 10 and 1000 times below this value.

Webb1.2. General features of a cleavage local criterion: From this short description, we need two criteria in order ta describe cleavage fracture : in a first step, microcracks are created. In a second, these microcracks become unstable. Experiments have been performed on mild steel by LOW 121 at very low temperature. Webb13 sep. 2006 · One criterion that the system must obey according to the model proposed is that 6 × (the theoretical shear stress of Co) is less than the theoretical cleavage strength (σ c) of the WC particles. Here we try to show that the ideas which apply to the WC-Co system can be applied to other particle-matrix systems.
