Description

Measurements of the Hugoniot Elastic Limit are compared with measurements of the strain-rate dependent compressive yield stress in several metals. The measurements are analyzed according to standard thermal activation theory. In several cases, only data from material from a single lot are used in the comparison. Results in Ti-6Al-4V, W, Ta, and 1018 steel are presented. It is shown that in all of the materials investigated the HEL is below the mechanical threshold stress, or yield stress at 0K. Comparison of the HEL with compression measurements at low temperature and quasistatic strain rates and with compression measurements at room temperature … continued below

Description

Measurements of the Hugoniot Elastic Limit are compared with measurements of the strain-rate dependent compressive yield stress in several metals. The measurements are analyzed according to standard thermal activation theory. In several cases, only data from material from a single lot are used in the comparison. Results in Ti-6Al-4V, W, Ta, and 1018 steel are presented. It is shown that in all of the materials investigated the HEL is below the mechanical threshold stress, or yield stress at 0K. Comparison of the HEL with compression measurements at low temperature and quasistatic strain rates and with compression measurements at room temperature and Hopkinson bar strain rates suggests that the strain rate associated with the HEL is on the order of 10/sup 4/ to 10/sup 6/ s/sup /minus/1/. 9 refs., 2 figs., 1 tab.
