Abstract

ABSTRACTA combination of dimensional analysis and finite element modeling was invoked to characterize the indentation behavior of transversely isotropic thin films on substrate materials. Through indentation simulations of over 13,500 combinations of properties for the thin film system, functional relationships that connect the indentation responses of the thin films with the elastic and plastic properties of the thin films were obtained. The forward algorithms that predict the indentation response characteristics from known material properties and the reverse algorithms that predict the material properties from known indentation responses were verified to be very accurate. Thus, the viability of using the indentation method to determine the elastic and plastic properties of transversely isotropic thin films on substrate materials was demonstrated.
