Metal Forming Processes

This research has focused on understanding multiscale deformation and failure behaviour of materials during conventional and unconventional forming processes. Some examples of the processes under investigation include sheet metal forming, incremental sheet forming, extrusion, and wire drawing. Experimental investigation are then used to develop computational frameworks for better predictions.
