| Abstract | A 3D multiscale method is proposed to model the residual stresses in multiphase materials under the hybrid-semiconcurrent multiscale framework. As an illustration, the quenching residual stresses in SiCa 2124Al composite are modeled. The total residual stresses are separated into the macro, elastic misfit and thermal misfit residual stresses by means of the present multiscale model. In this multiscale model, one macroscale model is connected to two microscale models via scale transition boundary conditions. The predicted total residual strains in the metal matrix and the reinforcing particles coincide with reported experimental data very well. The predicted total, macro, elastic misfit and thermal misfit residual stresses agree reasonably well with the reported experimental ones. The present model provides a new tool to gain a deep insight into the residual stresses in multiphase materials. (C) 2015 Elsevier Ltd. All rights reserved. |
