Stress intensity factors for an internal or edge crack in a circular elastic disk subjected to concentrated or distributed loads
Abstract
Stress intensity factors for an internal or edge crack in a circular elastic disk subjected to concentrated or distributed loads are obtained using the singular integral equation technique. First, a solution for the uncracked case is obtained using the complex variable method, and then employing the superposition technique the crack problem is reduced to a perturbation problem. By integrating the dislocation solution along the crack, a singular integral equation is obtained, which in turn is solved numerically. The stress intensity factors are calculated for various crack geometries and loading conditions.
