The fatigue crack growth in D16AT aluminum alloy specimens with multiple stress concentrators in the form of holes is investigated experimentally. A generalized kinetic fatigue crack growth curve is obtained and the Paris equation coefficients are determined for a great number of cracks. It is shown that a general linear, semi-logarithmic relations...

In the case of cyclic loading of aircraft structures, fatigue cracks are initiated and grow in riveted joints, which may lead to a decrease in the residual strength and to the sudden widespread fatigue damage. This phenomenon is induced by multiple-site damage, which is usually described by statistical methods. Since the crack length in multiple-si...

Проведено втомні випробування зразків сплаву Д-16АТ з моніторингом деформаційного рельєфу поверхні поблизу концентратора напружень. Показано, що безпосередній оптичний контроль стану поверхні дає змогу визначити потенційні зони руйнування.
