摘要: Using Moors-Penrose inverse theory, a set of formulations for calculation thestatic responses of a changed finite element structure are give in this paper. Usingthese formulations in structural analysis may eliminate the need of assembling thestiffness matrix and solving a set of simultaneous equations.
