Extremum Principles for a Class of Dynamic Rigid-Plastic Problems.

Abstract

A number of extremum principles are developed for the acceleration fields associated with rigid-plastic dynamic loading problems. Major emphasis is given to global and local principles for mode solutions (where the spatial variables may be separated from time). The extremum principles are developed by first considering a simple model and then proved for structure of any configuration. The discussion is limited to problems in which the displacements are small. (Author)
