A crack in the shape of three-segment broken line subject to longitudinal shear wave (English)
0 references
The authors propose a solution for the problem of the determination of dynamical stress intensity factors for a crack in the shape of three-segment broken line. The crack is located in an infinite elastic medium. In the medium harmonic longitudinal shear waves are propagating. The initial problem is reduced to a system of three singular integro-differential equations with fixed singularities. For the solution of this system a numerical method is developed that allows the study of real asymptotics of unknown functions.
