The solution of structural class optimization problems. Part 2: Numerical examples

Earlier, the criterion of minimum material consumption was formulated within the design of the I-shaped bar width outline and the stability constraints or restriction to the value of the first natural frequency in one principal plane of the cross-section inertia. In the distinctive paper, we formulate a criterion for the minimum material capacity of the I-shaped bar with a variation in its thickness and outline of the width, with restrictions on the critical force value or restriction to the value of the first natural frequency in two principal planes of the section inertia. Numerical examples are presented. © Published under licence by IOP Publishing Ltd.
