Based on the viscoelastic behavior of grain boundaries, we proposed a new mechanism for rock damage induced by stress relief. In this mechanism, the normal and shear stiffnesses of grain boundaries change with geological time so that the state of ...

Using joint elements for a mechanical model of grain boundaries, we performed a preliminary 3D finite element analysis of uniaxial tensile fracture for specimen models of monomineral polycrystalline rock under the assumption that fracturing occurs...

In this study, we developed a method for creating on a computer a specimen of polycrystalline rock composed of monomineral, and using joint elements with normal (kn) and shear (ks) stiffnesses for the intergranu...
