Abstract:

A compliance study was made on a 4X biaxial specimen to determine the numerical factor in the expression used for the energy release rate for the biaxial brittle fracture specimen developed by M. J. Manjoine ASME paper 64-METS-3. The variation of the numerical factor with crack length or notch depth was also determined. For the standard geometry specimen, the factor was found to be .722. This vlaue is approximately the same as that determined in another recent study at the Research Laboratories by A. M. Wahl, M. M. Leven, and W. K. Wilson. WERL-8844-1. Author
