| Abstract: |
| Based on the design pattern of element computational module for open finite element system SiPESC.FEMS,a general computational framework of flat shell element is constructed in this paper.Considering a combination relationship of plate and shell element,as well as reusability and flexibility of programming,a pattern of builder in the software design is used to achieve different combinations for various elements.This framework which has good versatility and scalability provides a new way for developing finite element program.The finite element system can handle complex loads,boundary conditions,and implement structural analysis including different kinds of elements flexibly.The results of numerical examples are discussed and compared to the performance for the five kinds of flat shell elements constructed by using the method in this paper.It is aimed to provide reference for the structural analysis to select appropriate flat shell elements. |
