THERMOMECHANICALLY INDUCED WEAR AT HIGH SLIP RATE INTERFACES BETWEEN DEFORMING COMPOSITE MEDIA .2. NUMERICAL-SIMULATION

To simulate the thermo/mechanically/chemically dominated wear in very high slip rate interfaces involving heavily loaded deformable elastome ric composite media, Part 1 of this series develops the requisite mode ling scheme. Included is the development of a new Lagrange-Fourier for mulation for conduction and thermally induced material degradation-wea r in highly strained media. In this part, a specialized numerical proc edure is derived to handle the sharp thermomechanical gradients and co ncomitant thermo/mechanical/chemical degradation-wear. This is achieve d via a computationally efficient telescoping mesh enrichment scheme. The methodology self-adaptively accommodates the hierarchy of scaling levels in the problem and conforms to the rapidly moving zone of mater ial degradation-deposition and wear. To benchmark the modeling procedu re and associated numerical solution algorithm, a series of empiricall y verified parametric studies are included in the presentation.
