The project aims to establish an effective and efficient computational framework for the topological design of novel mechanical metamaterials considering both geometrical and material nonlinearities. This would overcome a formidable bottleneck in practical applications of metamaterials which are mostly based on linear elastic assumptions. The expected outcomes will be a new methodology and an advanced engineering design tool that can be used for the development of new classes of metamaterials with exceptional mechanical properties (eg negative compressibility or negative Poisson’s ratio) over a large strain range. Such novel metamaterials would have many important applications, particularly in biomedical and defence industries.

该项目的目的是建立一个有效的和高效的计算框架的拓扑设计的新型机械超材料，同时考虑几何和材料的非线性。这将克服超材料实际应用中的一个巨大瓶颈，因为超材料大多基于线性弹性假设。预期的结果将是一种新的方法和先进的工程设计工具，可用于开发在大应变范围内具有特殊机械性能（如负压缩性或负泊松比）的新型超材料。这种新型超材料将有许多重要的应用，特别是在生物医学和国防工业中。
