Structural integrity assessment from the aspect of fracture mechanics
Апстракт
An increasing diversity of operations and different materials, as well as different working conditions lead to various construction solutions. Structural design is the preparation of structures that shall be efficient in fulfilling anticipated exploitation conditions, both economically and safely, i.e. there will be no damage resulting in the loss of structural functionality in service. In practice, however, there are fractures that can occur during construction, assembly, and exploitation. Fracture may be caused by overloads, by static fracture, or by dynamic loads, and by fatigue. Upon calculation of static structural durability, normal and tangential stresses are taken into account, while the dynamic durability calculation defines structural resistance to crack formation and its propagation under dynamic loading. The aim of this paper is to demonstrate the possibility of applying fracture mechanics to structural integrity assessment. To this end, the basic concepts of linear elastic... fracture mechanics will be explained.
