Abstract
Abstract During a hardness test, a hydrostatic core and a plastic zone are formed under the impression due to the load. The size and shape of the hydrostatic core and the plastic zone are greatly influenced by the tested material, the loading force and the shape of the indenter. In this study, we examine in detail the characteristics of the hydrostatic core and plastic zone formed during a Brinell and Vickers hardness test with the same (bilinear) hardening material model and with the same load using the finite element method in the ANSYS environment. The results of our resarch is concluded that the characteristics under the indenter can be determined well with finite element modeling and in the case of the Vickers procedure, the ratio of the hydrostatic core to the plastic zone is greater for all loads as in the case Brinell method.
