Abstract

The classical theory of elasticity is not always applicable to the elastic-hereditary environments. The conventional destruction criteria (assumed stresses and assumed deformations) are acceptable under static loads, under cyclic loads they are of little use.

The applicability of generalized destruction criteria -entropic, dissipative type and the level of material damage has been considered for determining the durability of elastic-hereditary environments.

The analysis of elastic-hereditary environments durability was based on the entropic destruction criterion and destruction criterion by the extent of material damage. In both cases, experimental researches of macro-and micro-structures are required. The calculation of elastomeric constructions durability based on the destruction criterion of dissipative type is possible without experimental methods, using table values.

The example of calculation of durability in dangerous areas of elastomeric constructions destruction is given from the literary data. Coincidence of calculated and experimental results is satisfactory
