ComputingRésumé
This paper is concerned with the development of a new family of solid- shell finite elements. This concept of solid-shell elements is shown to have a number of attractive computational properties as compared to conventional three-dimensional elements. More specifically, two new solid-shell elements are formulated in this work (a fifteen-node and a twenty-node element) on the basis of a purely three-dimensional approach. The performance of these elements is shown through the analysis of various structural problems. Note that one of their main advantages is to allow complex structural shapes to be simulated without classical problems of connecting zones meshed with different element types. These solid-shell elements have a special direction denoted as the "thickness", along which a set of integration points are located. Reduced integration is also used to prevent some locking phenomena and to increase computational efficiency. Focus will be placed here on linear benchmark problems, where it is shown that these solid-shell elements perform much better than their counterparts, conventional solid elements.

New prismatic solid-shell element: Assumed strain formulation and evaluation on benchmark problems Conférence invitéeTRINH, Vuong-Dieu; COMBESCURE, Alain; TRINH, Vuong-Dieu; ABED-MERAIM, Farid (John F. ABEL and J. Robert COOKE / Internet-First University Press, 2008)This paper presents the development of a six-node solid-shell finite element called (SHB6) and based on the assumed strain method adopted by Belytschko et al. [2]. It is integrated with a set of five Gauss points along a ...

Article dans une revue avec comité de lectureTRINH, Vuong-Dieu; COMBESCURE, Alain; ABED-MERAIM, Farid (Viện Hàn Lâm Khoa học và Công nghệ Việt Nam, 2009)In this paper, the formulation of a new six-node solid–shell element denoted (SHB6) is proposed. This prismatic element is based on a purely three-dimensional approach, and hence has displacements as the only degrees of ...
