A new displacement bound technique, which is based on concept of Serving Trays admissible fields has been developed for rigid Plastic continua subjected to strong dynamic loading at large deflections, the lower hound obtained (2.11) depends on kinematic ally admissible displacement ui and kinematic ally admissible velocity ui* which must be chosen so that the condition (2.14) may Nightstand be satiafidc.Parameter T* would be determinated by maximizing the right hand side of (2.11).
