| Abstract: | We analyze the influence of the stiffness of a testing machine and the loading mode on the mechanical characteristics and resistance of metals to deformation in the case of nonmonotonic development of their elastoplastic deformation caused by cooling to 4.2 K and (or) the action of pulses of electric current. We propose an approach that enables one to reduce the value of a jump of loading caused by the action of a pulse of electric current for an arbitrary loading mode to the maximum possible value (for a constant strain rate and a small amount of elastic energy accumulated by a loading device).
