Design of Ethylene-Vinyl Acetate Copolymer Fiber with Two-Way Shape Memory Effect. [PDF]
Polymers (Basel), 2019 One-dimensional shape memory polymer fibers (SMPFs) have obvious advantages in mechanical properties, dispersion properties, and weavability. In this work, a method for fabricating semi-crystallization ethylene-vinyl acetate copolymer (EVA) fiber with two-way shape memory effect by melt spinning and ultraviolet (UV) curing was developed.

Two way shape memory effect in NiTiHf high temperature shape memory alloy tubes
Acta Materialia, 2019 Abstract Two-way shape memory effect (TWSME) in nano-precipitation hardened, Ni50.3Ti29.7Hf20 high temperature shape memory alloy (HTSMA) thin walled tubes and its thermal stability were investigated. Torsional TWSME was induced by repeated thermal cycling across their martensitic transformation under applied shear stress.

Observation of the two-way shape memory effect in an atomistic model of martensitic transformation [PDF]
Papers in Physics, 2017 We study a system of classical particles in two dimensions interacting through an isotropic pair potential that displays a martensitic phase transition between a triangular and a rhomboidal structure upon the change of a single parameter.
