Elasticity, ability of a deformed material body to return to its original shape and size when the forces causing the deformation are removed. A body with this ability is said to behave (or respond) elastically. To a greater or lesser extent, most solid materials exhibit elastic behaviour, but there Energy-Dissipation Performance of Combined Low Yield In view of the disadvantages such as higher yield stress and inadequate adjustability, a combined low yield point steel plate damper involving low yield point steel plates and common steel plates is proposed.
