Incipient cracking
WebCracking or pyrolysis, as it is otherwise known, is a complex phenomenon involving many reactions, intermediate species, and final products. In its most basic form it may be thought of dehydrogenation and C–C bond rupture. The reactions are highly endothermic and heat is needed to initiate and sustain them.

WebThat makes crack luminescence helpful for investigating the incipient crack opening behavior. Cracks can be detected and observed during operation of a structure, making it also very interesting for continuous monitoring. Crack luminescence is a passive method and no skilled professionals are necessary to detect cracks, as for conventional methods.

WebFatigue moves from incipient cracking to interconnected cracks and finally to spall. This occurs when cracks intersect surfaces, allowing chunks and platelets to be carried away by the lubricating fluid. Further rolling contact produces more and larger chunks and platelets.
