Once stress surpasses the elastic limit, the material yields. Microstructures rearrange, microcracks form, and soil grains slide past one another. When you remove the load, permanent residual strain remains in the material. Core Components of Plasticity Theory
because the direction of plastic flow frequently differs from the gradient of the yield surface. Hardening/Softening Rule
occurs when plastic deformation increases a material's strength (e.g., through compaction), while strain softening represents a loss of strength (e.g., during shear banding). 2. Theoretical Principles for Geomaterials
