Entropy and Material Instability in the Quasi-Static Mechanics of Granular Mediaion” anticipated in previous work (.). After a brief review of the maximum-entropy model, it is shown that a special case allows for nonconvex pressure-volume response of a kind that could lead to heterogeneous stress states in an isotropically compressed granular packing.

Interpretation of the Scale Effect in Perforation Failurecorrelation between hole strength normalized by the uniaxial compressive strength and hole size normalized by the square of the division of rock fracture toughness over its tensile strength. These findings can be used for constructing mechanical models to predict failure in small size holes such as perforations.
