Abstract:

How can we overcome the formability of materials beyond original materiality ? To answer this question, we have adopted “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.

Short Bio:

Dr. Choi is an associate professor in the department of materials science and engineering at Seou National University. He earned his BS degree from Seoul National University, MS degree from Stanford University and Ph.D. degree from MIT in Materials Science and Engineering. He conducted his postdoctoral research at Karlsruhe Institute of Technology in Germany and then worked as a prinicipal research scientist at Korea Institute of Science and Technology (KIST) before joining the Seoul National University. He is currently serving as editorial board members in several domestic and international journals. At present, his work focuses on developing advanced structure materials for extreme condition.
