Recent advances in metamaterials

• Proposers: Chao Gao, Filippo Berto.

• Summary: The study of metamaterials has been in a breakthrough in recent years due to the fast growth of additive manufacturing and computational modelling. For example, by rationally designing the geometry and pattern of metamaterials, researchers and scientists have achieved unusual material properties, such as negative stiffness, negative Poisson’s ratio, negative thermal expansion coefficient and negative refractive index. In addition, the explosion of novel designed metamaterials shows some very interesting and promising research directions on multi-functional materials including programmable, shape memory, reciprocal, electromagnetic, optical and active materials.

The minisymposium focuses on theoretical, numerical and experimental research on metamaterials, providing an international forum for researchers and engineers from diverse backgrounds to discuss the recent advances in this field. Topics of particular interest include (but not limited to):

1. Analytical and numerical modeling of metamaterials;

2. Experimental testing methods of metamaterials;

3. Fracture and fatigue behaviors of metamaterials;

4. Topology optimization of metamaterials;

5. Data-driven approaches to design metamaterials;

6. Multifunctional design of novel metamaterials.
