New Light on Weibull Theory.
Abstract
In 1939 Weibull applied weakest link theory to the interpretation of the variability of fracture stress of nominally identical specimens. He attributed this variation to the presence of sources of weakness, or flaws, that were given a strength, but no other physical properties. Accordingly, his theory rests primarily on the statistics of extreme values. It is now generally believed that the most important sources of weakness are microcracks. Thus an ideal statistical theory of fracture must take into account of fracture mechanics and material microstructure. Present paper outlines recent progress along these lines, and shows how the resulting more fundamental theories reduce to Weibull theory when certain simplifying assumptions are made. (Author)
