By using the expressions of Hartranft and Sih for the stress field at the tip front of an arbitrary crack. the problem of crack propagation under combined stresses in a three-dimensional medium has been discussed on the basis of ((T")~,,, theory and its modification, (tm )m.,r theory. General results have been obtained, calculations carried out for some special cases, and a comparison made with experimental data available in literature.

The effect of variation of stress frequency on fatigue crack propagation in 99.5% pure titanium, which has remarkable strain rate dependence in the plastic region and anisotropy, was studied. Fatigue crack propagation tests were carried out under four stress frequencies: two constant stress frequenc
In the paper, a new kind of stress singular element is introduced for crack problems. This kind of element is more simple and widely used than those presented before. In the paper, a cube with embedded circular crack and a first kind Benchmark problem are studied. The study shows that using quarter-
