The block medium is modeled by a discrete-periodic spatial lattice of masses connected elastic springs and viscous dampers. To describe the viscoelastic behavior interblock layers, rheological model internal friction with two Maxwell elements one Voigt element quality factor material as determining parameter proposed. Numerical experiments show that, within framework this interlayer model, it p...
