✦ Synopsis

Proceeding from the experimental observation that circumferenFia1 crack growth in circular cylindrical pipes subject to bending loads is associated with a constant crack tip opening angle, the JR curve is predicted in terms of the pipe and crack parameters. The predictions compare favorably with experimental results for 4 in (-10 cm) diameter pipes containing cracks with different sizes.
