Stability and convergence of sequential methods for coupled flow and geomechanics: Drained and undrained splits (2011, background): “Changes in total stress and fluid pressure are related to changes in strain and fluid content by Biot’s theory [4,5,25,55,56].”
A stabilized assumed deformation gradient finite element formulation for strongly coupled poromechanical simulations at finite strain (2013, methodology): “Whereas this generalized derivation for compressible constituents has been recently considered in [13], our new contribution here is that the infinitesimal version of this formulation is fully consistent with the classical small strain balance law in [1, 7, 29] and can also be consistently reduced t”
Relationship between the Soil-Water Characteristic Curve and the Suction Stress Characteristic Curve: Experimental Evidence from Residual Soils (2012, background): “In Bishop’s effective stress and virtually all the other effective stress approaches that follow (e.g., Houlsby 1997; Khalili and Kabbaz 1998; Borja 2006; Nuth and Laloui 2008), the degree of saturation, rather than the effective degree of saturation, has been used.”
A Continuum Model for Deformable, Second Gradient Porous Media Partially Saturated with Compressible Fluids (2013, unknown): “Also relevant in this context is the e ﬀ ort by [11] who uses a mechanical theory with strong discontinuities at a micro level to introduce an e ﬀ ective stress tensor at macro scale for partially saturated porous continua.”
Analysis of the solid phase stress tensor in multiphase porous media (2007, methodology): “Borja [34] uses the theory of mixtures to derive Biots coefficient in a case of partially saturated soils.”
Mathematical framework for unsaturated flow in the finite deformation range (2014, background): “Balance of linear momentum A thermodynamically consistent effective stress equation [52, 75, 76] may be written in terms of the total Cauchy stress tensor , effective Cauchy stress tensor 0, Biot coefficient B , pore water pressure p pw , and pore air pressure pa, as follows: D 0 Bp 1 , p D SrpC .”
