Abstract : This report summarizes research concerning a critical test of atomic-scale computer simulation applied to the mechanical properties of materials. Because of certain advantages of the interatomic potential of ionic solids this work confined to potassium chloride. The development and results derived from this research conclusively indicate that atomic-scale simulation has become a valid research tool for illuminating happenings on an atomic scale and for the quantitative measurement of fundamental strength parameters.
