Geotechnical materials like soils, rocks, and concrete behave differently than metals. Traditional linear elasticity models fail to predict their behavior under high stress. When stress exceeds a critical threshold, these materials experience permanent, non-reversible deformation known as plasticity.

For geomaterials like soil and rock, this plastic behavior is critical. A foundation may settle not only due to elastic compression but also due to the permanent rearrangement of soil particles under load. Similarly, a slope might fail because the shear stresses exceed the soil's strength, leading to irreversible, plastic flow. Therefore, understanding plasticity is essential for predicting long-term deformations and ensuring stability.
