On the capillary stress tensor in wet granular materials (2009, background): “t the water inside the sample is solely composed of capillary water as deﬁned in the pendular state, with a discontinuous liquid phase. Much attention has been given to these pendular liquid bridges, [20,21,22]. Their exact shape between spherical bodies is deﬁned by the Laplace equation, relating t”
Liquid bridges at the root-soil interface (2017, background): “At a critical point, when 2Lffiffiffiffiffiffiffi Volw3 p > 1, the liquid bridge breaks up (Willett et al. 2000).”
Wet granular materials (2006, background): “The detailed experimental analysis of the cohesion force due to the liquid bridge between two spheres is found in [21].”
Adhesive particulate flow: The discrete-element method and its application in energy and environmental engineering (2011, unknown): “[153] V*=0.”
Influence of liquid bridges on the mechanical behaviour of polydisperse granular materials (2006, methodology): “[21] used the Derjaguin approximation for the radii to formulate a rather complex expression for the capillary force that needs to be simplified for implementation in DEM simulations.”
