Abstract
A topological modification method for structural variations of finite element system is;studied in this paper. The Moore-Penrose (M-P) inver se theory and a new factorization of a stiffness matrix are used. A se t of explicit formulations of variations are obtained. Two numerical e xamples are given to illustrate the validity of the present method. Co pyright (C) 1996 Elsevier Science Ltd.
