Abstract

The applicability of Johnson's equation for the potential drop to three specimen geometries is demonstrated. In addition, some remarks are made concerning the influence of crack length and specimen width on the resolution of the potential method.

Keywords:
fractures (materials), crack propagation, potential theory, specimen geometry, influence of dimensions on sensitivity
