Abstract

We study regularities of the development of the shape of the front of corner cracks under conditions of thermal and thermomechanical cyclic loading. The influence of loading factors on the stability of the shape of the front of a tensile crack is analyzed for specimens made of ÉI698 and ÉI617 alloys.
