Probabilistic Approach for Modeling of Aggressive Environment Influence on Creep Rupture

Last modified: 2013-02-10


the new method of modelling aggressive environment influence on creeprupture is suggested. This method is based on introducing of a notion of structural elementsand postulating elementary creep properties of these ones. The equations of behavior of aspecimen as a whole are based on the behavior of the elements. The various problems ofuniaxial loading are considered. It is shown that due to failure of some elements the field ofstresses may become nonequal and a surface of failure may appear. As a criterion offailure of specimen, the lost of stability in developing of this surface is accepted.
