CALCULATION OF CRACKS IN METAL STRUCTURES OF TRANSPORT INFRASTRUCTURE FACILITIES
Annotation
An actual approach to solving problems of the theory of cracks related to the so-called “extremal problems of mechanics” is presented. The problem of “brittle fracture” for a flat element in the presence of a rectangular crack in it, is considered. An analysis of the fracture change dynamics is carried out based on a mathematical model in partial derivatives. The calculations are performed with specific parameters of the material, in particular aluminum, of the elastic element and the load. The obtained results lead to conclusion on importance of geometric arrangement of the elastic elements in metal products of objects of transport infrastructure monitoring.
