We have carried out new experiments on the mechanical behavior of methane hydrate, extending our previous low temperature study (Stern et al., Science, vol. 273, p.1843, 1996) to higher temperatures. Samples are synthetic polycrystalline aggregates of pure methane hydrate molded as cylinders about 60 mm long and 25 mm in diameter with an initial porosity of about 30%. Pressurization to remove this porosity and deformation experiments to measure strength were conducted in a standard triaxial gas deformation apparatus, with the pressure vessel immersed in a cryostatic reservoir. Samples are encapsulated in an indium jacket. Internal methane pressure to the sample is controlled through a separate pore pressure line. Differential stress is applied to the end of the sample by a piston moving through sliding seals into the vessel. Stress is measured with an internal force gage.
