| The contact analysis of deformable bodies is one of the major research areas in finite element analysis. However, little work has been done in developing a solution to the problem of transient contact, due to the difficulty of establishing a stable solution. In relation to the tire industry, the satisfactory analysis of transient contact is of growing importance as the demand for increased ride comfort, but lower tire rolling resistance is imposed.;In this context, the purpose of this work is to develop a finite element procedure that solves transient contact problems subject to time dependent boundary conditions. Therefore, to adequately pursue this study, two contact procedures were implemented in ADINA: the Lagrange multiplier method and the penalty function method. Included in this work are several numerical experiments which illustrate the capabilities of the schemes to analyze sliding/rolling contact over a bump or hole. |
