      Optimization of blast-resistant structures for combat vehicles allows for maximum protection when constrained by additional weight. Livermore Software Topology and Shape Computations (LS-TaSC) optimization software is a constraint-based hybrid cellular-automaton tool that could be used to design optimum solutions. This software takes into account size, shape, topology, and topometry (changing of element properties on an element-by-element basis). The optimization is achieved by designing for a uniform internal energy density while constraining responses such as plastic strains and Von Mises stresses. New constraints added to the LS-TaSC optimization software allow a user to specify a maximum deflection with regard to a specified mass fraction and casting direction. If a realistic mass fraction and deflection constraint combination is specified, the model will be successfully altered until a uniform internal energy density is met, thereby minimizing mass and deflection. Another beneficial feature is the addition of a casting feature, which allows users to specify the face that is to be optimized. This report explores the utility of the enhanced LS-TaSC optimization software and its applications to the U.S. Army Research Laboratory (ARL) researchers for creating optimum lightweight blast-resistant structures for future and current vehicles.
