elastoplasticity

Elastoplasticity describes how materials deform under stress. When a force is applied, a material initially stretches or compresses elastically, meaning it returns to its original shape once the force is removed. However, if the force exceeds a certain limit, the material undergoes plastic deformation, causing permanent shape change. This concept helps scientists and engineers predict how materials behave under different loads, ensuring safety and durability in structures and products. Essentially, elastoplasticity combines elastic (reversible) and plastic (permanent) behaviors to model real-world material responses accurately.
