IL cav_un_auth*0212008 Zowe J. DE 12C IAA1075707 GA AV CZ cav_un_auth*0012793 AV0Z1075907 We formulate two problems of optimal design for mechanical structures in unilateral contact: the truss topology problem and the material design problem for elastic bodies. In both cases we consider general multi-load formulations, where for each load-case we may have different set of contact constraints. Both problems can be rewritten as mathematical programs, which only differ in the character of the input data. We propose an iterative optimization algorithm based on penalty-barrier methods.
