Materials exhibiting high elasticity obey Hooke's law
The elastic behaviour of rubber under compression is the same as its behaviour under tension
The damping capacity of a material is due to its plastic deformation
The stress required to cause plastic flow in polycrystalline material is higher as compared to monocrystalline materials due to the presence of grains of different orientations
