A New Method of Sensitive Analysis Based on the Weighted Inverse Topological Change Method

Abstract:

Using the weighted inverse theory of matrices and the weighed inverse topological change method of finite element structures, a set of formulae used in the sensitivity analysis of the parameters of a structure are presented. Combined with the previous work of the author, it can analyze the static modification of the structures efficiently. The all formulae of this method are explicit ones and have advantages of simplicity and easily operation on the computer. An example is given to demonstrate the valid and the efficiency of the formulae.
