Abstract: | Approximate solutions ofJ integrals under plane loadings (modes I and II combined) and antiplane shear loadings (mode III) are obtained for bodies
with central through cracks of power hardening materials, by using a perturbation method. The obtained calculating formula
is very simple and a comparison with available results shows that the formula enjoys quite good accuracy and is suitable for
engineering uses. |
