    Origami Structures: from shopping bags to sandwich composite plates and shells

    Dr. Zhong You, University of Oxford Department of Engineering Science

    In recent decades origami folding, a traditional Japanese art form of paper folding, has been of increasing interest to mathematicians and engineers. Mathematicians are more interested in the geometrical aspects of origami objects such as foldability of origami patterns, especially foldability of developable surfaces. Engineers, on the other hand, are finding that traditional geometry and folding used for artistic paper models can be readily parameterised and applied to the development of new structures and devices. Since most of the sheet materials used in engineering applications are relatively rigid in comparison with paper, particular attention has been drawn on to rigid origami, a subset of origami that permit continuous motion between folded states along the pre-determined folding creases without the need for twisting or stretching of the facets. This allows the patterns to be manufactured from modern materials such as plastic, metal, or carbon-fibre sheets, producing patterns that are sufficiently strong and durable to be of use in large-scale applications.

    In the talk, I shall start with a mathematical problem of folding a rigid shopping bag, followed by a brief introduction on the modelling of origami motions using mechanism theory. I shall then present the concept of the origami crash boxes and beams with potential application for energy absorption structures in transport vehicles. Finally, I shall outline my most recent work on sandwich composite structures with origami core structures.
