Abstract:

The paper presents results concerned with the use of perturbation method in optimal design of structures. An essential attention is given to optimization problems described by non-homogeneous boundary value problems for ordinary and partial differential equations. Different schemes for application of perturbation method in eigenvalue problems and in two dimensional optimization problems with unknown boundaries are described. Some aspects of obtaining successive approximations to optimal solution are given. The efficiency of perturbation technique application is illustrated by solving some particular problems. Some conclusions concerning practical application of the method and accuracy of used two-term expansions are drawn. Author
