For the illustrations of both approaches optimum configurations of fixed area open- ing in the loaded along a outline square plate were calculated. It is shown that the optimum project for the case of the fixed opening and the changing external loading differs from the project where it is taken into consideration that the loading is fixed and the opening is made in an originally solid plate. INTRODUCTION Analysis of publications dealing with the questions of deformed construction optimisation show, that on the whole are they devoted to elastic construc- tion. If the existence of inelastic deformati
