A progressive crack-tip strain approach to fatigue crack propagation is presented. Localstrain damage accumulation curve for crack initiation is used as a "cyclic damage accumulation" and "fracture criterion" in the heavily deformed region, R,?, just adjacent to the crack-tip. The changes of cyclic

The stress intensity factors for a thermal crack problem are computed directly from the crack tip singular field as it was embedded in a specialized crack-tip element. The method gives accurate results without modeling a very refined mesh near the crack tip and without evaluating additional line and

The stress-singularity at a crack tip moving arbitrarily in an elastic plate under plane strain conditions is investigated. By formulating the wave-equations in a polar coordinate system attached to the crack-tip, it is found by an asymptotic analysis that the angle-dependence of the singularity is
