Room temperature tensile and bend test results are reported for etched specimens taken from beryllium sheet. Three groups of approximately thirty specimens each, taken parallel, perpendicular, and at 45 deg to the rolling direction, were prepared and tested under identical conditions. There is a wide scatter of tensile results in all groups, the maximum scattering being approximately 33% of the mean value for the ultimate strength, and approximately 100% of the mean value for the elongation at frac ture. The mean value for the 0.2% tensile proof stress does not vary with direction of testing but the scatter of results in all groups is about 50% of this value. The bend-test results show slightly less scatter than the tensile properties. The elongation at fracture in tension increases in an approximately linear relationship with the calculated true fracture stress and the maximum value of both occur where the texture most nearly approaches a basal plane layer texture. The elastic limit in bending is significantiy higher than the 0.2% proof stress in tension, indicating that the elastic limit of beryllium is higher under complex stressing than under simple tension.
