| Abstract: | In the structural shape optimization (SSO) procedures,one of the main difficulties is to perform an accurate sensitivity analysis for the structural response with respect to some parameters.At present,the analytical,semi-analytical and finite difference methods are the most commonly used.In Hamilton systems,the sensitivity analysis of eigenvalue response was studied for piezoelectric laminated plates,and the governing equation of sensitivity coefficients of eigenvalue for piezoelectric laminated plates was ... |
