Hi, dear all,(adsbygoogle = window.adsbygoogle || []).push({});

recently study the solid mechanic continuity, keep reading about to solve large deformation of material, you will need so called "finite elasticity"

What is this finite elasticity refer to ?

"Finite elasticity is a theory of elastic materials capable of undergoing large deformations."

Erm, this sentence dont carry any meaning to me.

I thought elastic material should always be finite, as it has finite length, which allow us to have elasticity measurement. if i have large deformation, will it change anything about elasticity?or it refer to nonlinear elastic material?

mind to share?
