An elastic plastic damage formulation for concrete: Application to elementary tests and comparison with an isotropic damage model (2006, background): “kv0 and kv are the intrinsic permeabilities of the initial and damaged material, respectively, [36].”
Crack Effects on Gas and Water Permeability of Concretes (2009, background): “For low level damage, the relationships between permeability and diffuse damages have been studied experimentally after unloading [2] or under loading [1,3], and theoretically investigated [4].”
Effects and interactions of temperature and stress-level related damage on permeability of concrete (2007, background): “The first regime corresponds probably to the fluid percolation through both the pores and diffused micro-cracks in concrete (permeability increase governed by diffused damage [3,4,11]), the second one corresponds to the fluid flow through interconnected microcracks which initialise cracks formation,”
Eco-mechanical index for structural concrete (2014, background): “The latter mechanical property, which can also be related to cracking and permeability, is of fundamental importance to assess concrete durability [4].”
