The influence of several variables on the relation between COD and J is experimentally studied. These variables are temperature, geometry, strain-hardening exponent, slow stable crack growth, toughness value for each material and rolling direction. Four steels and a compacted cast iron were tested.
Finite element simulations of indentations on elastic and elastic-plastic materials have been performed to systematically study the effects of indenter geometry and mechanical properties, namely Poisson's ratio and the E/r y ratio, on the correction factor for Sneddon's equation used for analysis of
