文摘

J-integral estimates are developed for a beam containing a fully embedded horizontal crack. The J-integral is evaluated with the aid of a mechanics of material model developed elsewhere. Compliance method energy release rates are also developed. The analytical J-integral estimates are compared favorably to 2D finite element results. A maximum in the J-integral is shown to exist for cracks located at the beam mid-plane.
