Summary:

The pack method for determining compressive stress-strain graphs described in NACA Report No. 649 has been modified to extend its application to thinner gages and stronger materials. The principal modifications consisted in the provision of additional support against instability by cementing the specimens of the pack together with fused shellac and the provision of special clamps that hold the specimens in the pack together while the test is in progress. The shellac was found to increase the buckling load of the pack without any appreciable effect on the compressive stress-strain graph of the material. The extended pack method described in this note has made possible the application of stresses in excess of 220 kips per square inch to sheet material having a thickness of only 0.02 inch.
