Abstract

We formulate a mathematical model for the investigation of the processes of propagation of creepfatigue cracks in plates under block loading. The influence of the shape of loading blocks on the durability of structural elements is investigated and the the subcritical growth of creep-fatigue cracks in thin-walled structural elements is analyzed.
