Abstract

Mixed mode ductile fractures in thin sheets are shown to be possible. The staggered deep edge notch tension specimen enables J_p, the plane stress propagation value of the J integral, and d J/dα, the rate of increase in J with crack growth to be measured from the specific work of fracture. The J integral can also be separated into its two component modes J₁ and J_n. For the particular low alloy steel tested J_p is virtually independent of the mode of fracture, but for other materials J_p may be dependent on the fracture mode.
