Abstract： A solidshell element was introduced into explicit finite element method (EFEM) and locking pathologies were eliminated by employing twelve enhanced assumed strain parameters，which makes up the deformation limitations of solidshell element. Stress was updated through the corotational theory and radial return algorithm. Accordingly, a solidshell element analysis model based on EFEM was developed to account for plates and shells with large deformation. Standard benchmarks were exercised. The results show the high accuracy of the solidshell element. It also proved the efficiency of the proposed model in dealing with plates and shells exhibiting both large deformation and elastoplastic behavior.
