摘要：

By performing numerical calculations and experimentally using kinetic creep equations with scalar damage parameter correspondence of the falling part of "sigma - epsilon" diagrams and constant velocities of deformations to softening part of creep curve at corresponding constant stresses was established. Values of deformations corresponding to transition into the third softening stage of creep, are the quantitative indicators of survivability during shaping of constructional elements.
