The theory of cracks under longitudinal shear, as discussed in previous publications (1,2,3), is extended to bodies containing external cracks. It is possible, by an adaptation of the Schwartz-Christoffel transformation, to derive a general formula for finding the stress-intensity factor, a paramete

Dynamics of propagating shear cracks

The energy balance theory for the fracture propagation in brittle and quasi-brittle materials is discussed in a toroidal region around the crack periphery. A simple form requiring the dynamic solution valid only around the crack front and the knowledge of the fracture energy is presented. The result
