- Abstract
Summary: Finite element simulation is a powerful tool to study and predict the wear behavior of different mechanical systems. However, the high computational cost required to obtain accurate numerical solutions is a crucial aspect especially for large and complex models. The present study proposes a possible solution to overcome this limitation by exploiting the potentiality of the submodeling technique, whose application to wear problem is still rare in the literature. A global‐local approach for wear analysis is presented and validated for a simple pin‐on‐disk wear test. In a preliminary step, different submodeling techniques were implemented and compared. They differed for the quantity (nodal forces and/or displacements) transferred from the global model to the local one. Numerical models have been developed in Ansys® mechanical APDL using its new wear simulation and mesh smoothing routines. Results suggest that the proposed strategy can significantly reduce the computational cost of finite element wear models. Some interesting points on the use of submodeling in contact problems are also discussed.
