概要

Mechanical structures are designed to obtain minimal weight shapes by transforming the contours of the external boundaries and by shaping the vacant spaces of the internal regions. The given initial structural shapes of two-dimensional plates are transformed using the successive approximation in the steepest descent of the sensitivity function for the total strain energy of the structures constrained by the maximum equivalent stresses. The weight of the structural shape is minimized by the modification of the external contours, as shown by shape 4. The elements with very low values of the sensitivity function exist in the central region of shape 4. The structure of shape 4 is minimized by the shaping of the vacant spaces of the internal region, as shown by shape 8, which had about 14% less weight than shape 4.
