摘要：

Industrial processes involving composite materials need for efficient numerical simulations in order to optimize the process parameters. Even if the thermo-mechanical models are nowadays well established, efficient simulations need for further developments. In this work we are addressing some of these issues, in particular the one related to fast solutions combining model reduction and parallel time integration. A separated representation will be also proposed in the context of material homogenization allowing to alleviate the usual mesh constraints. (c) 2007 Elsevier B.V. All rights reserved.
