 Abstract :   

How can we overcome the formability of materials beyond original materiality? This talk will present a unique strategy from our group that can dramatically enhance the conventional limit of material formability. We introduced “simple geometric design concepts” that significantly enhance flexibility and stretchability of brittle structural materials. Geometrical design such as origami and kirigami provides us many examples of the formation of delicate and, detailed patterns leading to the effective distribution of stresses. Instead of process control and complex structure design, the simple juxtaposition of unit design can lead to simple, cheap and easily processed flexible, stretchable and deployable structures. In addition, newly developed computational approach expands our design dimension to the next level. We believe that geometrical modulation by controlled size, shape, and symmetry adds another dimension unleashing the limitation of conventional design space of structure materials.
