Abstract: In this work the problem of indentation of a half-space by a spherical rigid indentor is investigated using the finite element method.
A system of constitutive equations applicable to elasto-plastic materials subjected to large deformations is used to determine the deformations and stresses for the contact problems. These equations represent the simplest generalization for the large-deformation conditions of the classical theory of plasticity of metals based on the von Mises yield condition and the associated flow rule. The material formulation of the kinematical and dynamical relations will be used. These equations combine the kinematic and the isotropic strain-hardening models.
The results obtained from this work are compared with existing solutions for this problem that are confined to small strains and elastic, ideal-plastic materials.
