plasticity theories

Plasticity theories explain how materials, including metals and biological tissues, can permanently change shape or deform when subjected to stress or force. Unlike elastic materials that return to their original shape after the force is removed, plastic materials undergo a permanent change. This concept is important in engineering, where understanding how materials will behave under different loads is crucial for safety and design. In biology, plasticity refers to how organisms adapt to their environment, changing their function or structure in response to different conditions. Essentially, plasticity involves the ability to adapt and mold under pressure.
