Abstract
Experimental values of the fracture strengths of materials are commonly some two orders of magnitude smaller than the theoretical limit of approximately one-tenth of Young’s modulus (0.1E). The low experimental values are attributed to the presence in materials of cracks or crack-like defects which are able to provide high stress-concentrations. The cracks may be present ab initio as a consequence of manufacturing processes; they may be nucleated by plastic deformation; or they may be introduced deliberately, e.g. by fatigue, to provide standard precracks in testpieces.
