โœฆ Synopsis

The paper presents a general algorithm for computation of response sensitivity using Semi-Analytical approach and Hybrid Finite Elements. In particular, three types of two-dimensional quadrilateral elements based on the HellingerยฑReissner principle and its latter modiยฎcations have been chosen and implemented in the sensitivity expressions to demonstrate the improved performance of the algorithm. It is observed that the semi-analytical approach based on hybrid ยฎnite elements has the potential for obtaining cost-eective and accurate sensitivities and hence, is a good compromise between analytical and explicit ยฎnite dierence approaches.

This paper presents analytical sensitivity computation using hybrid ยฎnite elements. Expressions have been derived for analytical response sensitivities using two-dimensional hybrid elements developed on the basis of the modiยฎed HuยฑWashizu variational principle. Computational algorithms have been for
