摘要：

A procedure for extracting simple constitutive parameters from microindentation tests is described. The analysis used to interpret the indentation tests is based on the analysis of the spherical indentation test developed by Hill et al. for power law materials. Indentation tests are supplemented by scanning interference microscopy of the residual indented surface profiles and a method is suggested for using the residual surface profiles to estimate the actual contact surface. This, in turn, allows for the construction of the entire stress versus strain curve.
