Abstract
The difficulties involved in using valid ASTM K//I//c specimens for quality control purposes are described. It is shown from tests on steels and titanium alloys that values of K//I//c can be obtained at lower cost from small specimens. If fracture initiation occurs before general yield, K//I//c can be determined from the load required to cause crack extension. If fracture occurs after general yield, K//I//c can be determined from the critical plane strain crack tip opening displacement or from the notch root contraction.
