    ASTM Recommended Practice for R-Curve Determination (E 561) allows the use of either center cracked or compact specimens for determination of R-curves and Kc. A round-robin program to establish a Precision and Accuracy statement for ASTM E 561 was recently conducted on compact specimens. This paper presents R-curves and Kc data for two materials as determined from both specimen types. A discussion of the results is included.
