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.
