Our faculty member, Prof. Mehmet Barış Can Ülker, contributed to a study published in the International Journal of Geotechnical Engineering that investigates the hydro-mechanical response of multi-phase porous media using a coupled flow–deformation framework accounting for nonlinear constitutive behaviours.

The research introduces a nonlinear, coupled hydro-mechanical formulation based on three-phase extended poroelasticity and proposes a combined volumetric–deviatoric hardening law to describe stress–strain and volume change behaviour. Verification and validation analyses demonstrate the model’s ability to accurately capture the hydro-mechanical coupling in partially saturated soils, emphasizing the influence of hydraulic conductivity and suction variations on soil response.
