The annular crack problem for an isotropic elastic solid. (English) Zbl 0559.73090

This paper examines the problem of the internal loading of a flat annular crack located in an isotropic elastic solid. The surfaces of the annular crack are subjected to a uniform pressure. The analysis of the problem can be reduced to the solution of a system of triple integral equations. An approximate solution of this system of integral equations is used to generate the stress-intensity factors at the boundaries of the crack. The numerical results for the stress-intensity factors derived from the approximate solution are compared with equivalent results reported in the current literature.
