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

Using the single crack solution and the regular solution elf plane harmonic function, the problem of Saint-Venant bending of a cracked cylinder by a t ransverse force was reduced to solving two sets of integral equations and i ts general solution was then obtained. Based on the obtained solution, a me thod to calculate the bending center and the stress intensity factors of th e cracked cylinger whose cross-section is not thin-walled, but of small tor sion rigidity is proposed. Some numerical examples are given.
