The integral solutions for an axisymmetrical crack propagating at arbitrary speed in an infinite elastic solid are obtained as sums of associated static solutions and stress-waves integrals. For a circular crack running at a constant speed, exact dynamic solutions for crack shape and stress distribu
Stress intensity factors at any point on the crack front of penny and half-penny shaped cracks subjected to stress gradients are presented. The SIF's which are exact far a penny shaped crack are based on the well known solution for a point load acting normally to such a crack. The line load solution
Energetic arguments are used to discuss the growth of a penny-shaped crack situated within an infinite solid which is subject to tensile and shear stresses that are respectively normal and parallel to the crack plane. The most favourable growth mode is that for which the circular periphery becomes a
The shape of a penny-shaped crack located at the center of an elastic plate of finite thickness is related to the arbitrary axisymmetrical internal pressures applied to the crack surfaces in the form of a Fredholm integral equation, without using the methods of dual-integral equations. General expre
