The paper is devoted to development of new approach to topology optimization when stress and stiffness are considered simultaneously. The proposed method is demonstrated on the example of L-shape, MBB structuresrnand aircraft wing. An example of wing design illustrates the use of the developedrnstress-based topology optimization method in structural optimization of wing parameters.
