Analysis of the Conditions of Mechanical Destruction of Clathrate Hydrates Using the Graphoanalytical Mohr Method

The article considers the mechanisms of mechanical destruction of clathrate hydrates. To determine the conditions of destruction, the hydrate is considered as a quasi-brittle body with insignificant plastic deformation during destruction. The possibility of using Mohr's graphoanalytical method to determine the critical values of tangential stresses arising under complex-stressed volumetric action during destruction by the method of pressure reduction (depression dissociation) is shown. The application of Freudenthal's theory with the presence of a critical defect in the material as a basis for forming an understanding of the relationship between the strength of the material and defects and the mechanics of hydrate destruction as a quasi-brittle material is also considered.
