Definitions

Creep phenomenon is observed, first of all, in form of large and increasing in time deformations of solids. Operational loadings of structural elements are usually long-lasting, quite often acting in elevated temperatures, promoting large permanent deformations. Deformation process resulting from creep effect is defined as a process realized at long-lasting loadings at elevated temperature, during which the values of stresses and strains caused by structural loadings undergo change in time. Gradually developing damage of structure leads to the loss of material coherence. This process initialized at one, or few isolated points, spreads out and damage propagation finally leads to collapse of structure. This problem is of special significance in many branches of industry, beginning from energetics (steam boilers, turbine blades), thermal power plants (pipelines) in chemical industry,...
