CS Colloquium: Yingying (Samara) Ren (ISTA) - Computational Homogenization for Inverse Design of Surface-based Inflatables

Speaker: Yingying (Samara) Ren, ISTA

Talk Title: Computational Homogenization for Inverse Design of Surface-based Inflatables

Abstract: Surface-based inflatables consist of two nearly inextensible sheets joined along carefully chosen fusing curves, restricting expansion and inducing in-plane contraction and metric frustration. When inflated, these structures settle into a 3D equilibrium that balances elastic and pressure potential energy. In this talk, I will present our computational framework for analyzing and designing such inflatables to approximate a wide range of freeform surfaces while maintaining structural stability. Using numerical homogenization, we characterize periodic inflatable patches with arbitrary fusing patterns and seamlessly combine them through custom nonlinear surface parametrization methods. I will also discuss exciting future research directions in this space.
