METHOD OF DYNAMIC TEST OF SHEET MATERIALS WITH PULSE MAGNETIC LOADING Glushchenkov V.A., Ph.D. (Engineering), Associate Professor, e-mail: vgl.@ssau.ru Chernikov D.G., Ph.D. (Engineering), Associate Professor, e-mail: 4ernikov82@mail.ru Tiabashvili A.T., Master’s Degree student, e-mail: tiabashvili94@mail.ru Samara National Research University named after Academician S.P. Korolev, 34 Moskovskoye Shosse, Samara, 443086, Russian Federation Abstract In this article considered the scheme for the method of dynamic test of material properties using pulse-magnetic loading. It shown equipment and tool for the realization one of scheme. Performed of static and dynamic tests of sheet blanks. Forming limit diagram were constructed to evaluate the limit strain rate of the sheet material. As a result of measurement of the maximum velocity of the deforming tool has been defined – 15 m/s. Also it is shown that with increasing strain rate, increases the limit strain characteristics of the sheet material. Keywords forming limit diagram (FLD), dynamic loading, pulse-magnetic process
