Previous work done on this program under NSF grant                         DMR-8418097 dealt with the analysis of rolling contact                          deformation and fracture in steels and other materials.  The                    investigation combined elasto-plastic finite element and cyclic                 plasticity analyses using a fracture mechanics approach. The                    studies provided, for the first time, two-dimensional and three-                dimensional analyses based on cyclic constitutive                               relationships for pure rolling and rolling/sliding friction                     contact. The ongoing work seeks to more completely integrate the                mechanics and materials elements of the contact problem. Two                    aspects of this problem will be emphasized: one is the analysis                 of the idealized macrocontact; the other is the "near surface"                  effects produced by microasperities, lubrication pressure spikes                and frictional heating. This approach can accommodate realistic                 descriptions of material behavior and should lead to meaningful                 estimates of the contact distortions, cyclic plastic flow and                   residual stresses.
