Shape optimization of elastoplastic bodies obeying Hencky's law
Ivan Hlaváček · Applications of Mathematics · 1986
A minimization of a cost functional with respect to a part of the boundary, where the body is fixed, is considered. The criterion is defined by an integral of a yield function. The principle of Haar-Kármán and piecewise constant stress approximations are used to solve the state problem. A convergence result and the existence of an optimal boundary is proved.
