dc.description.abstractImpulse forming technologies can be used for shaping thin sheet metal parts, e.g. bipolar plates for hydrogen production. Thereby, the energy transmission behaviour to the sheet metals depends on actual process characteristics. In electrohydraulic forming with exploding wire, shockwaves are expected to cause transient pressure fields onto the forming area. This transient force or pressure action realises the punch while the die is a rigid part of the tool. Hence, one part of the forming tool does not feature a defined geometry. To understand the impact of such kind of punches the resulting strain field was mapped during electrohydraulic forming experiments. Different explosion wire materials were used to form 100 µm thin EN 1.4404 / AISI 316L stainless-steel sheet metals. The displacement was measured in-process with two laser triangulation sensors at different positions. This time and space resolving data was taken to represent the initial pressure and resulting strain distribution. The in-process measurements enable further optimisation of the process settings.en
