Size eect
This paper surveys the available results on the size eect on the nominal strength of structures — a fundamental problem of considerable importance to concrete structures, geotechnical structures, geomechanics, arctic ice engineering, composite materials, etc., with applications ranging from structur...

This paper surveys the available results on the size eect on the nominal strength of structures — a fundamental problem of considerable importance to concrete structures, geotechnical structures, geomechanics, arctic ice engineering, composite materials, etc., with applications ranging from structural engineering to the design of ships and aircraft. The history of the ideas on the size eect is briefly outlined and recent research directions are emphasized. First, the classical statistical theory of size eect due to randomness of strength, completed by Weibull, is reviewed and its limitations pointed out. Subsequently, the energetic size eect, caused by stress redistributions due to large fractures, is discussed.
