Predicting Fracture Resistance of Brittle Crystals



Grady S. White, Stephen W. Freiman, Lin-Sien H. Lum


A simple expression is derived relating fracture surface energy to easily measured material properties, i.e., the elastic Young's modulus and the equilibrium atomic plane spacing via a proportionality constant, k. This expression appears to be independent of the force law used to describe the bonding. Comparison with experimental values of fracture surface energy in a variety of cubic crystals the expression results in a strong positive correlation between calculated and measured values.
