How can elasticity of ductile material be double as brittle material?

Kiran

• Oct 13th, 2012

Molecular structure of ductile & brittle materials are different. Elasticity of both the cases can be well understood by tension/compression test, as you can notice ductile materials will yield & brittle will break.
Stress release in ductile is good in ductile.

Because the elasticity regains its shape and size.
