FRACTURE MECHANICS--ONLY A THEORY?

Fracture Mechanics, a new branch of the fields "Material Research" and "Theory of Strength of Materials" has during the last 5 years been introduced into the European Technical Literature. This branch deals with research on non-deformed brittle fractures in high tensile materials. Suitable functions have been established for different shapes of cracks but these functions include only the tension in the undisturbed zone and the shape of cracks, and it is thus possible to detect the stress intensity at the tip of the crack. The critical stress intensity during spontaneous crack widening (i.e. at failure of the test specimen or the structural member) is concurrently the material characteristic. This offers the possibility to calculate the allowable crack dimensions in structural members. So far the method is still limited to materials of ideal elasticity, i.e. to brittle materials, but there is reason to hope that it can be expanded to more common tough materials.
