“…First of all, a static contact between an aluminum half cylinder and a steel plate is considered. In order to validate the model developed in this study, a comparison of present model with experimental and numerical results of Doca et al [32] was made. In this case, the elastic-plastic contact of two bodies are treated without temperature variation and the effect of TCC is not included.…”

“…Due to the nonlinearity of the material behavior with plastic deformations, the experimental methods and the numerical calculations are used to determine the material deformation. In this situation, the correct characterization of the mechanical behaviour of the material is crucial.The detection of the curve of deformation with exactitude requires the modeling of several parameters [29][30][31][32][33][34][35][36].…”

This study presents the development of a thermo-mechanical simulation model for an elastic-plastic contact problem between a half cylinder and a plane plate. The set of equations was solved using direct coupling method by Ansys mechanical. The results obtained from the present numerical model of the structural contact without heat transfer are compared with those of analytical, experimental and other numerical models. Then, the contact problem was solved using a coupled thermo-mechanical model. Computational results showed significant effects of thermal consideration in the elastic-plastic contact problem. Large deformations of structure due to high temperature are predicted using the thermo-mechanical model with elastic-plastic deformations. This model is useful to predict deformations on the structural components due to contact at high temperature situation.

“…20 Doca et al studied the frictional contact problems between a mild steel cylinder and an aluminium alloy block undergoing nite elastoplastic strains, 21 and compared the predictions with experimental observations. 22 Chen et al found a possible rolling of an elastic cylinder adhering on an elastic substrate subject to a strain gradient and established a criterion for the initiation of rolling. 23 With regards to the involved materials having a nonhomogeneous characteristic, Meijers presented an asymptotic solution for the contact problem between a rigid cylinder and an elastic layer fastened to a rigid base, by assuming no friction and a long enough dimension to ensure a plane strain.…”
