O-Hyun Kwon, Jin-Ho Roh · MDPI AG · 2025
A hysteresis-inclusive constitutive model for SMPC hinges enables finite element prediction of recovered configurations and identifies design factors to improve shape recovery ratio.
Plain English summary
Why this matters
Key findings
- Fabric elastic energy is identified as a dominant driver of recovered shape in SMPC hinges.
- A constitutive equation integrating Mooney–Rivlin hyperelasticity, viscoelastic stored energy, and fabric hysteresis enables accurate prediction of recovered configuration.
- Finite element method analysis based on the model is validated against experimental results.
- Simulation results indicate significant design factors for increasing the shape recovery ratio of SMPC hinges.
Limitations
The abstract does not specify the range of hinge geometries, loading conditions, or the extent of experimental validation details; it also does not provide quantitative results in the provided text.
