✦ Synopsis


A three parameter fracture criterion which correlates the stress and the stress intensity factor at failure, is followed for the residual or fracture strength estimations of cracked con®gurations made of aluminum±lithium (Al±Li) alloys. The three fracture parameters are determined from the fracture data of Al±Li alloy center surface crack tension (SCT) specimens at cryogenic temperatures. It is found that the estimated fracture strength values compare well with the test results.
