Creep Damage Model Considering Viscoplastic Strain Rate and Energy Dissipation
ABSTRACT In the creep process of rocks, energy dissipation is the core driving factor of damage evolution. The initiation and propagation of microcracks within rocks, as well as the closure and penetration of pores, are all accompanied by irreversible energy dissipation, and the...
