摘要：
A new approach to extract the mechanical properties of ductile thin films on brittle substrates based on the representative strain (corresponding to the representative stress) has been presented in depthsensing indentation with finite element method (FEM).Forward and reverse analyses of high deformation symmetry numerical simulation of Berkovich indentation tests are used to determine mechanical properties of ductile films.The proposed reverse analysis provides a new solution for the initial yield stress (or the representative stress) and the strain-hardening exponent,given that the Young's mo...
