ON THE STRESS-CONCENTRATION IN THICK CYLINDRICAL-SHELLS WITH AN ARBITRARY CUTOUT

In this paper, based on the theory of thick shells including effects o f transverse shear deformations, a complex variables analytic method t o solve stress concentrations in circular cylindrical shells with a sm all cutout is established A general solution and expression satisfying the boundary conditions on the edge of arbitrary cutouts are obtained . The stress problem can be reduced to the solution of an infinite alg ebraic equation series, and can be normalized by means of this method. Numerical results for stress concentration factors of the shell with a small circular and elliptic cutout are presented.
