Abstract: Abstract The conventional constitutive models employed to describe rock mass creep behaviour associated with the squeezing mechanism are widely adopted in research and design practice. However, these models fail to explicitly replicate the 3-phase creep… read more here.

Abstract: We propose a linearized model for isotropic damage with strain-gradient effects in the small-strain isothermal regime. We account for pressure-confinement effects induced by spatial variations of volume changes, which might locally determine a self-healing-type behavior.… read more here.
