Optimal Structural Metamaterials for Launch Vibration Control

By controlling and optimally grading properties at the microscale, structural metamaterials can exhibit exciting and unexpected emergent behaviour with applications across numerous fields of engineering. Using the numerical framework and optimization methodologies developed within our group, which will be elaborated in the talk, we have synthesized optimal metamaterials for compliance, morphing, thermo-structural response and many other fields. In this talk we will specifically consider the application of metamaterials to vibration control and mitigation for spacecraft structures during launch.

By demonstrating the complete design process from optimization to reconstruction to experimental validation it will be shown that the process is effective and offers a new approach for the design of spacecraft components.
