Shear strengths of solid methane and argon to 8 kbar at 77 K

Abstract

The shear strengths of solid argon and methane have been measured as a function of pressure at 77 K by a chamber-to-chamber extrusion process. The results for methane are new, while for argon some earlier work by Towle has been confirmed and extended. The initial shear strength of methane was found to be slightly larger than that of argon. At pressures above 1.5 kilobars argon has the larger shear strength. Indium was examined at room temperature and served as a standard of comparison. © 1971.
