Presented By: Aerospace Engineering
Chair's Distinguished Lecture: Computer Graphics-inspired Physics-based Simulation for Deployable Structures and Soft Robots
M. Khalid Jawed
Assistant Professor

Abstract:
Metamaterials (e.g. origami) and complex materials (e.g. biological, composite) have become integral parts of engineering with a broad range of applications: deployable structures, soft robots, stretchable electronics, wearable devices, and additive manufacturing. The large number of parameters governing their mechanics imply that an empirical trial-and-error approach is often impractical in designing functional smart structures. Fast and efficient computer simulations that create a ``digital twin" -- a virtual analog that accurately portrays the physics and mechanics of a structure -- are required to come up with structural designs that feature the best performance. We adopt a combination of physics-based and data-driven approach to modeling and optimization of smart structures. The physics-based methods are motivated by fast algorithms developed by the computer graphics community for animation of hair and clothes in movies. The data-driven methods draw inspiration from the tools in the nascent field of machine learning and artificial intelligence. This talk will illustrate two representative structures designed in this paradigm. (1) A bacteria-inspired soft robot that leverages structural buckling to control its swimming direction. (2) Thin deployable shells and gridshells that pops-up from a planar shape to a preprogrammed 3D shape.
