Hi, dear all, 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?
