11. Factors Influencing Shear Strength
Shear strength is influenced by various factors including soil composition, initial state, and structure. The Mohr-Coulomb failure criteria offer a framework to understand when materials fail due to specific combinations of normal and shear stress. Understanding these factors is essential for geotechnical engineering and soil mechanics.
Sections
Shear strength is influenced by factors such as soil composition, initial state, and structure.
