报告摘要:
Thin elastic plates and shells subjected to compressive stress can undergo a wide variety of geometry-dependent mechanical shape instabilities. Inspired by many examples in nature where such processes are used to provide adaptable form and function, our group seeks to develop new approaches to synthetic materials systems with tailored and reconfigurable 3D shapes and properties. In particular, we have studied the use of photo-patterned and photo-responsive polymer films to prepare polymer films and multilayers containing stimuli-responsive elements. This approach provides access to both smoothly curved plates with programmable and reconfigurable Gaussian curvature, and sharply folded films suitable for reversibly self-folding micro-scale origami. The folding of curved surfaces is largely unexplored, but our initial investigations have revealed simple geometric principles for designing bistable shell structures connected by rapid snap-buckling transitions.
