Title: An Investigation of Enhanced Formability in AA5182-O Al During High-Rate Fre-Forming at Room-Temperature: Quantification of Deformation History

Following the two prior publication of PNNL Pulse-Pressure research in the Journal of Materials Processing Technology, this manuscript continues to describe PNNL’s advances in getting a better understanding of sheet metal formability under high strain-rate conditions. Specifically, using a combination of numerical modeling and novel experiments, we quantitatively demonstrate the deformation history associated with enhanced formability (~2.5X) in Al under room temperature forming.
