In this paper, a new method for contactless high-speed testing of spherical micro samples by an electrohydraulic punch is introduced. The punch transfers the punching force incrementally to extrude the samples stepwise in dies with high aspect ratios. The sample’s material behavior is characterized by analyzing the deformation behavior between the extrusion steps and at different forming stages.enhigh-throughput material testingbulk formingmicro parts620670conference contributionhttp://hdl.handle.net/2003/37000http://hdl.handle.net/2003/37001
