| Abstract |
The rationale for the prospects of using the physical and mathematical theory of metal creep
in creep computations is carried out by a comparative analysis of the classical phenomenological and
physical and mathematical metal creep theories. On the example of the description by both theories
specific results of non-stationary creep experiments and analysis of the theories equations it is shown
that implementing the physical kinetic equation for the actual structural parameter of the material,
namely the scalar density of immobile dislocations, makes the physical and mathematical theory universal for solving non-stationary metal creep problems with multiaxial loading, when change, including abruptly, temperature, forces and loading rates. |
