A Method for Measuring Metal Sheet Bending under Impact of Electrohydraulic Forming

CZU 53.082.52:621.7.044.4

An experimental method has been developed to measure the metal sheet bending under its deformation. This method requires a relatively low cost for its implementation and efficiency of obtaining final results. The credibility of this method is substantiated, and the measurement error is determined. The method has been tested through analyzing metal sheet deformations by shockwaves generated by an electrical discharge in water.
