Investigation of contact behaviour of elastic layered spheres by FEM

Abstract

Normal contact behaviour of two elastic-plastic layered spheres was investigated by the Finite Element Method (FEM) and role of specified distinct particle's parameters was examined. The particle consists of a relatively stiff elastic skin-layer and relatively soft core substrate. Modelling is made in the frame of the Hertz theory applied to homogeneous spheres. Contact force-displacement relationship as the main target of applications in DEM is basically studied by the FEM analysis. Contact behaviour is defined by the dimensionless effective elasticity modulus expressed finally in terms of elasticity modulus of core substrate and thickness of the layer
