文摘

Cyclic fracture behaviour of through-wall cracked welded straight pipes was studied. Cyclic failure load reduced to 78.5% of the monotonic failure load for resisting 50 loading cycles. NG welded specimens showed more energy absorbing capability and crack growth resistance. Crack growth under load-control was unstable and specimens failed by sudden collapse.
