Insights into Cruciform Sample Design



Adam A. Creuziger, Mark A. Iadicola, Timothy J. Foecke, Evan Rust, Dilip K. Banerjee


Four different cruciform sample designs, based on the work of Abu-Farha et al, were studied in this paper. The original design of Abu-Farha was validated at room temperature for a thicker sample, and two modified sample geometries that would permit thinner samples were developed. Finally, an optimized thin sample was tested that performed nearly as well as the thicker sample. The cruciform sample geometry can lead to stress limited constraints in the center pocket region, and strain limited constraints near the re-entrant notches. Balancing these two constraints determines the success or premature failure of the sample.
