• Is Matric Suction a Stress Variable (2008, methodology): “The relationship between matric suction and suction stress is nonmonotonic for sandy and silty soils and monotonic for clayey soil, yet can be unified by the concept of suction stress conceived by Lu and Likos 2006 .”
• Tensile Strength of Compacted Clayey Soil (2015, background): “In recent years, the suction stress characteristic curve has been proposed to represent the state of stress in unsaturated soil, and suction stress was considered as the dominant parameter controlling soil tensile strength (Lu and Likos 2006; Lu et al. 2009).”

• Unified Effective Stress Equation for Soil (2020, background): “From the existing suction stress data (e.g., Lu and Likos 2006; Lu et al. 2010), the higher the clay content, the lower (more negative) σsdry.”
• Root-soil mechanical interactions during pullout and failure of root bundles (2010, methodology): “…is the total normal stress, ua is the air pressure (assumed equal to 0 in our calculations), uw is the pore water pressure, and c is the effective stress parameter assumed to be a function of the degree of saturation [Lu and Likos, 2006] with values ranging between 0 (dry) and 1 (fully saturated).”

• Relationship between the Soil-Water Characteristic Curve and the Suction Stress Characteristic Curve: Experimental Evidence from Residual Soils (2012, background): “Furthermore, most data used for the validation of the effective stress for unsaturated soils are from tests on transported soils (Bishop and Blight 1963; Khalili et al. 2004, Lu and Likos 2006; Nuth and Laloui 2008; Lu et al. 2010).”

• Tensile Strength of Unsaturated Sand (2009, methodology): “According to Lu and Likos 2006, suction stress has four components arising from various physical and physico-chemical mechanims: van der Waals attractive forces, electric double layer forces, tensile pore water pressure, and surface tension.”
• Generalized Soil Water Retention Equation for Adsorption and Capillarity (2016, background): “…ll ri gh ts r es er ve d. understanding the mechanical behavior of unsaturated soil such as shear strength (Fredlund et al. 1996), deformation (Lu and Kaya 2012), and effective stress (Khalili and Khabbaz 1998) or the suction stress characteristic curve (SSCC) (Lu and Likos 2006; Lu et al. 2010).”
