Key Features:

• Behavior of Materials: Elasticity actually mean that material can tolerate some temporary deformation and return to its original form once external forces removed.
• Stress-Strain Relationship: It obey Hooke's Law under Elastic Limit Basically, it means that deformation of a material is proportional to applied stress at least for values of stress within the elastic limit.
• Elastic Limit: The maximum amount of stress that a material can undergo without leading to permanent deformation.
• Typical Applications: The importance of elasticity becomes clear from the various engineering and industrial applications. In mechanical equipment such as springs and shock absorbers, elasticity guarantees a reliable mode of working under cyclical loads.

In civil engineering, steel and some other materials are selected based on their elastic property for taking up forces in bridges and buildings, thus preventing sudden failure. Not only are such materials useful in constructing dams, bridges, and buildings, but they are also useful in aerospace and automotive applications since these elastic materials help in making components more durable and resilient to dynamic forces. Continuous research is being carried out to improve elasticity through better alloys and innovative processing methods, leading to enhanced performance in demanding applications.
