In the recent past inaccuracy problems have been reported that arise when computing shape design sensitivities by the semi-analytical method. Since both the analytical and the global ΓΏnite-di erence method do not show these severe inaccuracies, it has been concluded that these errors are due to the
## Abstract Dependence of dynamic response of nonlinear mechanical systems on design variables is analysed. An adjoint variable method is used to derive firstβ and secondβorder derivatives of measures of dynamic response with respect to design variables. A computational algorithm is presented for n
