Methods for the determination of static and dynamic stresses in bodies with subsurface cracks

Limit Equilibrium of a Cylindrical Shell with Longitudinal Crack with Regard for the Inertia of the Material

“…In turn, these stresses promote the development of fracture processes in the vicinity of stress concentrators (pointed technological cuts, crack-like defects, and inclusions) and in many cases serve as the main cause of fracture. This is why the problem of prediction and evaluation of the reliability, serviceability, and durability of elements with stress concentrators require the construction of adequate mathematical models (and, in particular, the models that take into account inertial properties of the material and the time dependence of the load) accompanied by the development of methods aimed at the solutions of the problems of dynamic fracture theory [2,4,11].…”
