Abstract
A computer programme has been developed to solve for torsion of solids of revolution by numerical solution of an exact boundary integral equation which is valid for any shape and any degree of connectivity. The programme gives solutions directly at the boundary and requires only simple boundary data defining the contour to be input. The basic integral equation has been differentiated to give internal stresses directly, when required.
The computed results have been checked experimentally by photoelastic techniques and are compared with analytical solutions for the circular cylinder and the cone.
Comprehensive charts are given for stress concentrations in stepped shafts with circular fillets and fillets constructed of two blending radii. Fillets giving stress concentrations close to unity have also been investigated.
