Inelastic
Inelastic refers to a type of material or substance that does not easily return to its original shape or size after being deformed by an external force. This property is characterized by a lack of flexibility or elasticity, leading to permanent changes in the material's form. Inelastic materials typically exhibit a higher resistance to deformation compared to elastic materials, making them useful for applications where maintaining a specific shape or structure is important. Examples of inelastic materials include certain metals, ceramics, and plastics.
