Mathematical model of corrosion damage tolerance for structures loaded by varying load

Аннотация

The mathematical model is presented by a set of probabilistic equations, the solution of which is the essence of methods for determining the permissible (which does not influence to fatigue life) corrosion damage and residual lifetime of the damaged structure. The model can be used to estimate the state of an object according to detected damage, to ground the inspection periodicity, and to estimate the volume of repair works under known predictions for corrosion development, and to determine whether the used practical approaches meet safety standards.
