Simulation of Frictional Wear with Account of Temperature for Polymer Composites
Статья в журнале
The paper proposes a finite element approach with a mathematical model and an algorithm for simulating the wear of polymer composites in friction joints with account of temperature. The polymer interaction with a counterpart is modeled by solving a stress-strain contact problem with regard for the physical nonlinearity of deformation in polymer composites. The contact temperature is estimated by solving a nonstationary heat conduction problem with regard for mechanical-to-thermal energy conversion and for heat loss via convection without any additional heat exchange assumption. Reasoning from the temperature calculated, the state of finite elements associated with the properties of a polymer composite is changed (elastic modulus, heat capacity, yield strength, tensile strength), and those elements for which one of the fracture criteria holds are deleted as “worn”. The mesh is thus rearranged into a new one with the current stress-strain and temperature values interpolated to it. The approach is applied to analyze the effect of temperature and roughness on the friction and wear of homogeneous polymer composites and polymer coating–steel substrate systems. The results of simulation are compared with experimental data for ultrahigh molecular weight polyethylene in dry sliding friction with a steel counterpart.
