Abstract :
A theoretical method of describing the emission ability increase, enabling one to find the factor of transformation of deformation energy into the electron emission is considered in the present article. As the authors are basically interested in the description of dynamic effects under the action of stress, at numerical analysis of current density, being the result of the action of nonstationary temperature stress, the authors consider stresses exceeding the strength, which do not lead to destruction under dynamic action
