Mohr-Coulomb failure criterion

The Mohr-Coulomb failure criterion is a principle used in geology and engineering to predict when materials like soil or rock will fail or break under stress. It considers two main factors: the amount of stress applied and the material's internal resistance to sliding along surfaces, which depends on cohesion (how well particles stick together) and friction. Essentially, it helps determine the conditions under which structures can safely support loads without collapsing, helping engineers design safer buildings and slopes.
