Abstract
A method for determining contact characteristics occurring in spherical indentation depending on the properties of an elastic-plastic material governed by the hardening Hollomon power law is proposed. In this case the empirical Meyer law relating a spherical indentation load with an indentation diameterdis used. Basically, the Meyer law is not related to the mechanical characteristics of the test material. The study used the relations between the strain hardening exponentnand the Meyer law constant obtained by S.I. Bulychev. The effects of «sink-in / pile-up» are considered. It is shown that there is no need to define Meyer law constants. The scope of application of the proposed equations is defined. A comparison of the results obtained with the published results based on the finite element (FE) analysis is given.
