Structural Heterogeneity of Soil Clods: Correlating Weibull Parameters to Fracture Surface Topography

LA Pires Barbosa, HH Gerke - Available at SSRN 3998891, 2022 - papers.ssrn.com
Planes of weakness (ie cracks) existing in the soil matrix propagate creating fracture
surfaces and fragmenting the clod into smaller clods. The fracture topography (ie roughness) …
