Inelasticity refers to a property of materials or systems that do not return to their original shape or state after a force or stress is removed. Unlike elastic materials, which exhibit reversible deformation, inelastic materials undergo permanent changes. This means that some of the energy applied during deformation is dissipated, typically as heat or sound, rather than being stored and released.

In physics and engineering, inelasticity is a crucial concept when analyzing the behavior of materials under stress. For many materials, there is an elastic limit. Below this limit, the material behaves elastically, returning to its original form. However, if the applied stress exceeds this limit, the material enters the inelastic region, and permanent deformation occurs. This phenomenon is often referred to as plastic deformation.

Examples of inelastic behavior can be observed in everyday materials. When a metal paperclip is bent, it retains its new shape, demonstrating inelasticity. Similarly, clay or dough, when molded, does not revert to its original form. In economics, the term "inelastic" is used to describe demand or supply that is not very responsive to changes in price. For instance, if the price of a necessity like essential medicine increases, demand may not decrease significantly, indicating inelastic demand. Conversely, if demand or supply changes drastically with price, it is considered elastic. The study of inelasticity is vital for designing structures, predicting material failure, and understanding market dynamics.
