How does rubber differ from most metals
WebDec 1, 2015 · At one extreme, a rubber band is an example of a material with low stiffness—it can withstand a lot of deformation and still return to its original dimensions when the load is removed. On the other hand, a high-stiffness material like diamond will elastically deform only a small amount when load is applied.
