The theory of elasticity and plasticity is a branch of physics and engineering that deals with the study of the behavior of materials under external loads. Elasticity refers to the ability of a material to return to its original shape after being deformed, while plasticity refers to the permanent deformation of a material without failing.

where $\sigma$ is the stress, $E$ is the modulus of elasticity, and $\epsilon$ is the strain.
In contrast, plasticity theory deals with materials that undergo permanent deformation without failing. Plastic deformation occurs when the material is subjected to a stress that exceeds its yield strength. The plastic behavior of materials is characterized by a non-linear stress-strain curve, which can be described by various mathematical models.
$$ \sigma = \sigma_y + H \epsilon^p $$
One of the most commonly used models is the Prandtl-Reuss model, which assumes that the material behaves in a perfectly plastic manner.
In the theory of elasticity, materials are assumed to behave in a linear and reversible manner. This means that the material will return to its original shape when the external load is removed. The elastic behavior of materials is characterized by Hooke's Law, which states that the stress (force per unit area) is proportional to the strain (deformation per unit length).
