A semiempirical procedure has been developed to determine the stresses in a thin-wall cylinder extending from a block cavity and subjected to cantilever loading. A theoretical analysis produced the equations for direct bending stress and radial stress. The local stresses were experimentally determined via strain gage techniques. In addition, the experimental results indicated the angular location of the maximum local stress. Combination of the total axial stress and the radial stress sensibly provide the maximum shear stress applicable in design.
