ABSTRACT

Emerging fabrication process for mechanical structures can offer advantages in terms of reduced energy requirements or increased design flexibility. However, the body of knowledge lacks the design consideration of such components to optimize the final part’s characteristics. Researchers have established best practices and design considerations for traditional manufacturing processes to reduce the product cycle and increase the efficiency and quality of final components. This talk will discuss the implementation of design-for manufacturing approach for Origami sheet metal (OSM) folding fabrication process.

OSM folded structures are promising topological entities that can be folded from a flat metal sheet to complex 3-dimensional geometrically constrained structures. It can offer a reduced demand on the manufacturing and design resources such as energy, heavy machinery, and complex die design. In addition, the OSM structures can exploit materials with high strength-to-weight ratios such as aluminum and stainless steel. Despite its potential, there is a lack in the understanding of the parameters affecting the topological re-configurability and load bearing capabilities for full scale OSM structures. Specifically, the folding performance through the thickness of metal materials with focus on failure mechanism along the fold lines. The technique of combining folding structures and metal materials poses challenges that require further investigation. This talk discusses the extension of the Origami technique to the fold forming of sheet metal products represented in modeling approach and design considerations for the topological variations, the geometrical validity, and mechanical performance analysis.
