Contact including coupling between mechanical and thermal fields constitutes a complicated problem because the mutual influences between displacements or strains and temperature are manifested in many different ways. A detailed description of various issues related to the thermo-mechanical coupling in contact can be found in the monograph “Computational Contact Mechanics” by P. Wriggers. In this paper a formulation of a beam-to-beam contact element for the coupled thermo-mechanical field is presented. Contact surfaces are considered ideally smooth, so that the heat transfer due to radiation and convection in the micro cavities is neglected. In the physical model of the beam material, only the linear thermal expansion is included and all the physical parameters are treated as independent of time and temperature.

Abstract
Contact including coupling between mechanical and thermal fields constitutes a complicated problem because the mutual influences between displacements or strains and temperature are manifested in many different ways. A detailed description of various issues related to the thermo-mechanical coupling in contact can be found in the monograph “Computational Contact Mechanics” by P. Wriggers. In this paper a formulation of a beam-to-beam contact element for the coupled thermo-mechanical field is presented. Contact surfaces are considered ideally smooth, so that the heat transfer due to radiation and convection in the micro cavities is neglected. In the physical model of the beam material, only the linear thermal expansion is included and all the physical parameters are treated as independent of time and temperature.Pubblicazioni consigliate
