Experimental and theoretical methods for determining the parameters of equations of mechanics media failure for fatigue and creep

To assess the strength and resources of responsible engineering objects developed a model of the damaged environment consisting of three interrelated components: relations defining viscoelastoplastic material behavior, the kinetic equations of damage accumulation and the criterion of strength of damaged material. Shows the experimental and theoretical methods of determining the parameters of the equations of mechanics of the damaged environment to describe the degradation of the initial strength properties of structural materials (metals and their alloys) in the mechanisms of fatigue and creep. A comparison of calculated and experimental data have shown that the developed model reliably describes the damaged environment durability of structures under the joint action mechanisms of fatigue and creep.
