Abstract

J -integral and crack-associated displacement formulas are derived for a notched round bar in tension. The formulas are applicable for a wide range of flaw length to bar radius ratio. The formulas are particularly useful for calculating J from single load-displacement record obtained as part of fracture toughness test.
