Abstract: F48.00015 : Thermally responsive mechanical metamaterials
2:03 PM–2:15 PM
We present mechanical metamaterials capable of shape transforming under a given change in temperature. Compliant unit cells are programmed in period architectures to achieve desired deformation of extension and compression, as well as capable of uniform scaling and shearing. A broad diversity of basic shape transformations is reproduced, each with adjustable level of thermal expansion. Others more complex feature traits of shape reversibility and trajectory tracking that can be functional for deployable satellites, morphing components, and actuation devices.
