Method to calculate bending center and stress intensity factors of cracked cylinder under Saint-Venant bending

Using the single crack solution and the regular solution of plane harmonic function, the problem of Saint-Venant bending of a cracked cylinder by a transverse force was reduced to solving two sets of integral equations and its general solution was then obtained. Based on the obtained solution, a method to calculate the bending center and the stress intensity factors of the cracked cylinder whose cross-section is not thin-walled, but of small torsion rigidity is proposed. Some numerical examples, such as circular cylinder with an eccentric crack, petaloid cross section cylinder with an eccentric crack, and so on, are given.
