Dynamic Properties of Mechanical Metamaterials: Optimization and Experiment

该项目的目的是通过拓扑优化来开发新型机械超材料，以操纵弹性波和声波的传播。机械超材料具有奇异的动力学性能，在噪声管理、振动控制和国防等领域有着广泛的应用。即将开发的计算工具和优化算法将与加法制造无缝集成，使最终用户能够以有效的方式表征、设计和制造下一代机械超材料。该项目的成果对澳大利亚知识经济的长期和可持续发展具有重要意义。

The aim of this project is to develop novel mechanical metamaterials through topology optimization for manipulating the propagation of elastic and acoustic waves. Mechanical metamaterials achieve exotic dynamic properties, which have many applications ranging from noise management and vibration control to defence. The computational tool and optimization algorithms to be developed will seamlessly integrate with additive manufacturing to enable the end-users to characterize, design and fabricate the next generation of mechanical metamaterials in an effective way. The outcomes of this project offer significant benefits for the long-term and sustainable development of knowledge-based economy in Australia.
