Nośność rozdzielcza pierścieniowej tarczy kołowo-symetrycznej ze sztywną inkluzją

The loading at which the continuous solution breaks for systems made of ideally elastic-plastic material is called decohesive carrying capacity. In paper [7] as one of examples of systems in which it may occur, an infinite sheet with circular rigid inclusion, extended at infinity with uniform traction q was given. Here an annular disc with finite outer radius is considered. The possibility of its further work, after decohesion is discussed. The case of very narrow disc, which can be totally in plastic state before decohesion is also considered. For all types of discs their decohesive carrying capacity as a function of their dimensions and Poisson's ratio is determined.
