Bending Limits in Friction Stir Processed 5083 Aluminum Plate
Bending performance of aluminum plates at room temperature can be enhanced by friction stir processing (FSP), which can locally anneal and refine grain size at the pre-tensile side of the plate. Plates with thicknesses from 8-25 mm of AA 5083 have been friction stir processed and then bent into a v-die to investigate the increase in ductility that results from FSP. A finite element model was also developed to predict bending limits of the friction stir processed plate, as well as an unprocessed plate. The material property gradient in the friction stir processed plate was obtained by machining tensile specimens at various locations through the thickness of the plate and then testing the specimens to generate flow stresses for the model calculations. This approach allowed for good agreement between experiments and model prediction of plate bending limits.
