Elastic behavior ::superelasticity
, 2022 Superelasticity refers to the unusual ability of certain metallic alloys to undergo very large recoverable deformations. This unique property is linked to the existence of a crystallographically reversible stressinduced martensitic transformation (Otsuka

Surface effects on the superelasticity of nanohelices [PDF]
Journal of Physics: Condensed Matter, 2012 Helical nanomaterials with superelasticity have a wide range of promising applications in micro-/nanoelectromechanical systems. Based on the theory of surface elasticity, we present a nonlinear rod model to investigate the superelasticity of nanohelices. Our results demonstrate that the superelasticity of nanohelices exhibits a distinct size dependence
