The mathematical model of consecutive energy transformation of the capacitor bank in discharge systems is developed and tested, and it displays for the first time the two-dimensional interaction of electromagnetic, hydrodynamical and elastoplastic processes of pulse deforming of metals. The model primarily determines the pressure field dynamics in a restricted technological scope, with account of current elastoplastic deformation of a blank, wave diffraction and interferece, and also cavitation of a fluid and its striking off the surface of the part being deformed depending on parameters of the power unit, properties of the environment, configuration and geometrical sizes of discharge chambers. It allows forecasting the conditions for effective use of the energy generated by a capacitor bank of pulse electrohydraulic plants for intensifying plastic deformations and facilitating the shape forming of sheet high-strength steels grades DP780, BH240, BH210, HSLA350 during their cold pulse forming Product Description popup.authors Барбашова Г.О.
