Title: Shear Strength. Analogy to the Friction Model Description: Description of the friction model as an analogy to the shear strength of soils. Sánchez Romero, FJ. (2022). Shear Strength. Analogy to the Friction Model. https://riunet.upv.es/handle/10251/18... DER Automatic description: In this video, a professor from the Polytechnic University of Valencia explains the shear strength of soils using the Mohr-Coulomb failure criterion, comparing it to the friction model. The presentation is structured in four sections: introduction, description of the Mohr-Coulomb criterion, analogy with the friction model, and conclusions. The Mohr-Coulomb criterion is fundamental in soil mechanics, since the generally anisotropic and heterogeneous behavior of soils requires estimating the stresses and strains generated by various loads to compare them with the soil's failure capacity. This criterion relates the maximum shear stress to normal stresses and is influenced by soil cohesion and the angle of internal friction. The analogy with the friction model helps to understand the interactions between soil particles, considering normal and tangential forces. A block on a horizontal and inclined plane is analyzed, demonstrating how frictional forces impede movement and how the relationship between tangential and normal stresses is determined by the maximum angle of inclination required to maintain equilibrium. In conclusion, the importance of shear strength for evaluating the suitability of soil under applied loads is highlighted, and the understanding of the strength parameters that define this strength is deepened. This is essential for defining safety and stability in geotechnical engineering problems.
