The analysis of solids and structures in multiphysics conditions has been given increasing attention during the recent years. A large number of problems considered only a decade ago as very difficult to solve can now be analyzed with relatively little computational effort. However, there are many problem areas where significant advances are still needed for effective simulations.
The objective in this presentation is to summarize our research efforts to advance the state of computational simulations in engineering and the sciences. We present our recent developments regarding the analysis of transient and wave propagation problems [1-3], the analysis of shells [4-6], the prediction of more accurate stresses , the use of interpolation covers to increase the convergence of solutions , and the coupling of structures to general fluid flows and electromagnetic effects .
The field of multiphysics is very large and we must expect that multiphysics problems will be tackled to an increasing extent: in engineering, where new designs require a deeper understanding of performances, see e.g. [10, 11], and in the sciences, because a deeper understanding of nature through simulations will create important advances – for example, in the field of medical sciences in particular.
