- The paper presents application of an energy-based finite element and a local relaxation method to computer calculation of deformation of a ring made of hyperelastic material. The present study considers a surface friction mechanism. This mechanism is a physical phenomenon counteracting the relative motion of the contacting bodies. Friction causes loss of energy the dissipation of which is a result of wearing out of the bodies' surfaces and heat emission. This directly affects the shape of the deformed body. The above statements are confirmed by the results of computer calculation performed for rubber ring with rectangular cross-section. Rubber is a nearly incompressible material and, therefore, requires application of special mechanical models of the material properties as well as proper calculation methods. Implementation of energy-based finite element and local relaxation method enables studying the ring deformation with consideration of nonlinear properties of rubber and its displacements in the platering contact plane, according to the value of a friction coefficient between rubber and the plate material. Application of energy method resulted in determination of the work of friction forces and the energy density distribution of volumetric and deviatoric strain. It also simplified energy analysis of the surface friction mechanism and influence of the friction coefficient value on the process of the ring deformation.
