- Relationship between the Soil-Water Characteristic Curve and the Suction Stress Characteristic Curve: Experimental Evidence from Residual Soils (2012, methodology): “Lu et al. (2010) proposed and validated a closed-form equation for effective stress in unsaturated soil in which the contribution of matric suction, χðua uwÞ can be defined by a sole function of matric suction or the effective degree of saturation.”
- Estimating water retention curves and strength properties of unsaturated sandy soils from basic soil gradation parameters (2017, methodology): “The definition of suction stress shows fair validations in different soils from clays to sands [Lu et al., 2010; Oh et al., 2012; Oh and Lu, 2014] and using Se as the v value can also be seen in Vanapalli et al.”

- Constitutive modelling of state-dependent behaviour of unsaturated soils: an overview (2020, background): “This is because this equation properly considers at least two different effects of suction path: (a) altering the suction stress and hence effective stress proposed [47]; (b) affecting suction hardening [38].”
