Inertial model of enhanced plasticity at the superconductivity transition

It is shown that in the model of low-temperature plasticity based on athermal depinning of the dislocations from local obstacles the inertial effects associated with the acceleration of the dislocations during their translatory motion between the obstacles form the definitive factor in the dynamic depinning force. Dependences of the discontinuity of the deforming stress at the N--S transition on the differences of the electronic drag constants ..delta..B = B/sub N/ - B/sub S/ in the N and S states, the mean distance between obstacles, their effective power, and the deforming stress are calculated.
