A method of calculating design sensitivities for non-linear continuum systems is presented. The sensitivity process is established through operating on the converged solution of a set of non-linear equations which have been solved by the finite element method. The method is applied to structural elasto-plastic problems with particular emphasis being placed on the load sensitivities with respect to geometry. Comparisons are made using forward and backward approximations on the two results. Furthermore this thesis is concerned with the development and application of a numerical design model for shape optimization of pressure vessel structures under internal pressure. The main objective is the minimisation of the maximum plastic strains such that optimal designs can be produced.
