Evaluation of formability enhancement of aluminum alloy sheet in electrohydraulic forming process with free-bulge die

Electrohydraulic forming (EHF), a high-speed forming process, deforms a material by using high-pressure shockwaves in a fluid-filled chamber. When a material is deformed at speeds higher than 100 m/s, its formability can be improved due to the high-strain rate effect. This allows for the production...
