Scientific-Technical Section


The possibility of localization of fracture of piping by controlling crack trajectory is considered. A method including creation of controlling barrier layers is proposed and the area of occurrence of the physical mechanism of control of crack trajectory is established. The trajectories of the controlled cracks are determined theoretically and experimentally.
