| Outline of Final Research Achievements |
Although a study on practical use of the methane hydrate as a substitute for petroleum energy resource is in progress, the estimation of elastic properties of methane hydrate is still not enough. Therefore, we determined the general elastic properties of gas hydrates associated with the present results of elastic constants for methane-oxetane hydrate, and estimated the elastic properties and the structural stability of methane hydrate under shear stress and high pressure.
As a result, it is found that the elastic properties of the gas hydrate are more dependent on the size and the shape of the gas molecule in hydrogen-bonded water cage than its structure, and the elastic constant related to shear stress for methane hydrate under shear stress becomes slightly small.
