Tb. Kermanidis et Fi. Mavrothanasis, BOUNDARY INTEGRAL FORMULATION OF CRACKED AXISYMMETRICAL BODIES UNDER TORSION, Theoretical and applied fracture mechanics, 19(3), 1993, pp. 195-206
A Green's function is used to formulate the torsion of axisymmetric bo
dies with internal or external cracks. Mode III stress intensity facto
rs K3 are obtained for a circular cylinder containing both internal an
d external circular cracks. While K3 for the internal crack tends to i
ncrease with increasing crack size, the opposite is found for the exte
rnal crack. Numerical results are displayed graphically.
