Viscoelasticity of Steel: Is it Right?

[lingesh]

Viscoelasticity is a property of a material that exibits both viscous and elastic properties..

When under load,within elastic limit,steel offers resistance to deformation (viscous) and regains shape after removal of load..So is it right to say steel is VISCOELASTIC in elastic limit?

No. Steel is not viscoelastic at ordinary deformation rates and does not exhibit viscous type behavior. The stress is strictly a function of the deformation and not the rate of deformation.
