OSTI ID:7348077
Room temperature notch tensile strength of two advanced structural grades of beryllium was determined at quasi-static and high strain rates. Results on P-1 hot isostatically pressed and S-65 hot pressed beryllium indicated that the ductility ratio of Gerard provides a more reasonable approach to design allowables for these materials than tensile elongations for tensile loading in the presence of notches. Ductility ratios of .138 for P-1 and .058 for S-65 were found to represent these materials adequately for values of the theoretical elastic stress concentration factor less than five.
