The yield surface shrinks, representing a loss of strength after peak failure. 3. Key Constitutive Models in Geomechanics
Plasticity in geomechanics refers to the permanent deformation of soil and rock under stress without failure. When a soil or rock sample is subjected to stress, it initially behaves elastically, meaning that it deforms reversibly. However, as the stress increases, the soil or rock begins to deform plastically, meaning that it deforms permanently without failing. This permanent deformation is a result of the rearrangement of the soil or rock particles, which can lead to changes in the volume and shape of the sample.

The most successful models, like the Cambridge Cam Clay models, incorporate the concept of , which defines a unique state where soil can deform continuously under constant stress and volume, and has greatly advanced the field.
