| Abstract Scope |
Crumple-formed structures have irregular, multiscale geometric complexity. Similar to periodic lattices, crumpled geometries may be tailored to applications requiring a high strength-to-weight ratio. Their inherently irregular geometries decrease the sensitivity of the relationship between macroscale properties and microscale manufacturing defects but also pose a unique challenge for the analysis of manufacturability using additive processes. This paper presents a preliminary study into the manufacturability of crumple-formed structures using a model reduction technique that preserves the robust bulk statistical properties of crumpled structures. Current approaches to manufacturability analysis lack dimensionality reduction techniques suitable for approximating the multiscale geometric complexity and irregularity of crumpled structures. Manufacturability predicted by the reduced order model is experimentally assessed by comparison between the simulated and manufactured crumpled geometries using image analysis techniques. As an alternative to conventional confinement-based crumple forming, additive manufacturing allows for increased geometric control and structural reproducibility. |
