A Piezoelectric Finite Element System Based On Internet And Component

Based on Internet and component, a novel piezoelectric finite element system is presented in this dissertation. Up to now, the most of the state-of-the-art piezoelectric finite element software was made by structural programming language, and they are very difficult to be reused and integrated, so component and three layers architecture attracts more and more attention and they are regarded as one of the best method to alleviate the software crisis. First, the developing approach of software and the evolvement of architecture were introduced, then the concept of COM and the database access technology especially ASP was discussed. Moreover, the method of developing COM component by using an available FORTRAN program is proposed, and then the distributed computation was realized. Finally, the afore-mentioned components were integrated into a system; A B/S application and distributed computation on Internet were realized; By using ADO and database the active web pages were actulized and a circumstance of study finite element was provided.
