摘要

In the paper, a coupled thermo-hygro-mechanical model is formulated within the framework of l thermomechanics of partially saturated porous media in the sense of Blot 's theory [1]. An anisotropic plasticity-damage model is employed in conjunction with the fracture energy concept for the description of the pre- and post-cracking behaviour of concrete. Nonrecoverable strains are associated with a nonrecoverable increase of the porosity. The effect of cracking on liquid permeability is accounted for by relating plane Poiseuille flow through discrete Fracture zones to the degree of damage in the continuum model. [References: 4]
