STRAINS SUPERPOSITION PRINCIPLE WHEN CONSTRUCTION ELEMENTS HAVE STRUCTURAL DAMAGES

Abstract

Rheological state equations of materials are obtained on the base of the principle of the superposition of fraction creep strains. Boltzmann the first applied this principle when the fraction strains were independent of the value and duration of the rest stresses increments. The structural damages generate the dependence of these strains on all fraction stress increments. The quasilinear rheological equation is obtained on the base of the Boltzmann principle modification.
