Origami, the ancient Japanese art of paper folding, broadly refers to a set of techniques to transform planar sheets into three-dimensional (3D) structures. Fabricating arbitrarily complex 3D geometries requires the ability to change the intrinsic curvature of initially flat structures, while simultaneously limiting material distortion to not disturb the surface features. Advances in computer science, number theory, and computational geometry have paved the way for powerful design and analysis techniques using origami concepts. Modeling and simulation of origami thus becomes very important for realizing complex mechanical structures.

In this seminar, I will talk about different Origami modeling and design approaches, used to approximate intrinsically curved surfaces. The next section will focus on simulating intermediate state of folding by using rigid origami model along with the model kinematics. Finally, I will highlight on the practical aspects that are relevant in the development of advanced materials with these techniques.
