Abstract:

Based on the open style finite element system SiPESC.FEMS, a computational software framework of laminated composite plate and shell elements is constructed in this paper according to the classic model in order to select composite elements properly in engineering analysis. With the employment of the combinational method of plate and membrane elements, a software design pattern called builder is proposed for laminated multiple composite plate and shell elements. This software design framework possesses good versatility and extensibility. Furthermore, it can handle complex boundary conditions of load and displacement, and be applied to 3D laminated composite structures with different ply angles and materials as well. Five kinds of laminated composite plate and shell elements are implemented in this simple and practical unified software framework. Numerical examples of these elements are presented to validate their precision and the advantage of the combination method.
