... experimental work at the U.S. Naval Research Laboratory in Washington, D.C. led, in 195 7 4 , to a theoretical formulation of fracture that continues to find wide application. Irwin showed that the ... geometry factor, and c is the crack half-length. K 1 is called the “stress intensity factor.” There is an impor- tant reason for the stress intensity factor to be defined in this way...
