Determination of Fracture Toughness and K-R Curve for 2524-T3 Aluminum Alloy

Abstract:

In the present work, the resistance to crack extension of 2524-T3 aluminum alloy under Mode I loading was studied by using the middle-cracked tension M (T) specimens. The curve, plane-stress fracture toughness and apparent plane-stress fracture toughness were calculated by test data. The average value of measured fracture toughness at room temperature was 161 MPam^1/2. The results and conclusions can be referred in airplane skin design.
