Abstract : Permanent plastic deformation of impulsively loaded aluminum alloy (3003-H14) cantilever beams at temperatures up to 400 F was studied. Results were compared to the predictions of the basic rigid-perfectly plastic theory and to those of a rigid-plastic theory that included the strain rate sensitivity of the yield stress and changes in the geometry. At 400 F the experimental results differed appreciably from those of the basic theory and were in good agreement with those of the rate dependent theory. The latter results were also relatively insensitive to the detailed analytical form of the strain rate law used in the analysis. (Author)
