This test method covers the determination of plane-strain (chevron-notch) fracture toughnesses, KIv or KIvM, of metallic materials.

1.1This test method covers the determination of plane-strain (chevron-notch) fracture toughnesses, KIv or KIvM, of metallic materials. Fracture toughness by this method is relative to a slowly advancing steady state crack initiated at a chevron-shaped notch, and propagating in a chevron-shaped ligament (Fig. 1). Some metallic materials, when tested by this method, exhibit a sporadic crack growth in which the crack front remains nearly stationary until a critical load is reached. The crack then becomes unstable and suddenly advances at high speed to the next arrest point. For these materials, this test method covers the determination of the plane-strain fracture toughness, KIvj or KIvM, relative to the crack at the points of instability.

(B)Y* = exp[C0  + C1 r + C2 r2  + C3 r3  + C4 r4 ], accuracy ±0.5 %.
(C)Estimated from finite element analysis (3), and extrapolated equation from Ref (4). Accuracy for 0.3 ≤ r ≤ 0.85 is ±0.5 %.
(D)Extrapolated from equations in Ref (4). Accuracy estimated to be ±0.5 % for 0.2 ≤ r ≤ 0.85.
(E)Equation from Ref (4). Accuracy estimated to be± 0.5 % for 0.15 ≤ r ≤ 0.6.
