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.ContentsPart I: Quasi-statics of contact interactionOptimal contact pressure and optimal punch shapeInfluence of forces applied outside contact regionShape opti...
