The subcritical growth of semi-elliptical surface cracks in the front face of a cylindrical disk was calculated. The disk represents a part of a turbine rotor. The stress intensity factors, which are the basis for the calculations presented here, were given in a former paper [l]. The load steps cons

This paper describes a numerical procedure to model the crack front evolution of initially arbitrary shaped planar cracks in a three-dimensional solid. The influence of a bimaterial interface on the fracture path of a semi-elliptical surface crack in a three-dimensional structure is examined. The an
The weight function for the surface point of a semi-elliptical crack in a plate of finite thickness has been derived and tested against numerical data available in the literature. Derivation was accomplished by using the universal weight function form and two reference stress intensity factors. It w
