Resumo:   Abstract. Wear is a failure mechanism that takes place on the contact interface of solids in relative motion. For instance, in the oil & gas industry wear can be observed on chain links and connectors of the mooring system. In this work, we analyze two standard mooring connectors which are modeled as elasto-plastic solids. Numerical simulations of a gross slip regime yielding plastic strains and wear are carried out on Abaqus. A Python subroutine is implemented for the optimal discretization of the contact surface. The objective of this analysis is to identify how relevant is the wear phenomena on the failure of the mooring system of offshore platforms on ultra-deep sea locations. The methods employed for the evaluation of the wear volume are the Archard method and the Dissipated energy method. The results show that the development of plastic strain on the contact surface of the mooring connectors acts as a catalyst of the fretting wear process. Keywords: Contact Mechanics, Plastic Strain, Fretting Wear, FEM
