ACCEPTED MANUSCRIPT ACCEPTED MANUSCRIPT Highlights ¾ Instrumented indentation is performed on various metals and alloys. ¾ Frame compliance of the instrument is taking into account for accurate measurements. ¾ A new relationship between the elastic recovery energy to the total work-of-indentation ratio and the applied load to the square of the contact stiffness ratio is proposed. ¾ A proportionality factor has been found by both finite elements method and inverse analysis for the material presenting an intermediate mechanical behavior. ¾ The values of elastic modulus obtained from the new relationship are in a very good agreement with the theoretical values given in literature.
