About This Book

This monograph studies optimization problems for rigid punches in elastic media and for high-speed penetration of rigid strikers into deformed elastoplastic, concrete, and composite media using variational calculations, tools from functional analysis, and stochastic and min-max (guaranteed) optimization approaches with incomplete data. The book presents analytical and numerical results developed by the authors during the last ten years.

Part I:Quasi-statics of contact interaction

1Optimal contact pressure and optimal punch shape

The problem of optimization of the pressure distribution under a rigid punch that interacts without friction with an elastic medium filling the half-space is investigated with the help of classical calculus of variations [14, 64, 75, 116, 117]. The punch shape is accepted as a desirable design variable, and the root-mean-square deviation of the pressure appearing under the punch from a certain specified distribution plays the role of a minimized functional. In this case, the total forces and moments applied to the punch are assumed as specified, which leads to limitations imposed on the pressure distribution by the equilibrium conditions. It is shown th...
