I need more clarification from all,
I think, you are thinking about elastic strength. elasticity
is different from elastic strength.
Of course steel has high elastic strength(youngs modulus)
but it has low elasticity. It couldn't get original shape
still the deformation is lower than rubber and elastomer
materials.
for an example take a piece of rubber and steel
under application of load rubber and steel both gets
deformation but rubber only can get its original shape after
removal of load(though the load is much lower than steel)
steel needs more load to deform because of high elastic
strength only.

Please anyone send me previous papers of ONGC (Mechanical Engineering) at my email id jtndrkmr.vermaapril@gmail.com. Please help me.
