Inverse design and additive manufacturing of shape-morphing structures based on functionally graded composites
Hirak Kansara, Mingchao Liu, Yinfeng He, Wei Tan · arXiv · 2023
An inverse design method controls local bending stiffness in functionally graded composites to produce kirigami-like shape-morphing structures that match target 3D shapes in simulations and experiments.
Plain English summary
Why this matters
Key findings
- Inverse design is achieved by introducing distributed modulus in functionally graded composites to match a target bending stiffness profile.
- Modulus distribution along the elastic strip is controlled slice-by-slice using the rule of mixtures.
- A range of shape-morphing structures with different Gaussian curvatures are produced.
- Measured morphed shapes show very good agreement with target structures.
- Compressive rigidity and specific energy absorption of FGC-based hemi-ellipsoidal morphing structures are examined numerically and validated against experiments.
Limitations
The abstract does not specify the range of loading conditions, durability/cycling performance, manufacturing constraints, or which physical environments are considered for the claimed multi-physical environments.
