Abstract

A series of unistructural materials was used to investigate dependence of fracture energy upon crystal bond ionicity. Fracture energy values obtained from indentation measurements were found to agree with those obtained from a simplistic sine function force law calculation. In addition, an indentation procedure to determine whether environments enhance fracture is discussed.
