Nowadays, there is no doubt that we have been into the big data era. Under such a circumstance, developing future smart materials and structural systems is largely dependent on big data analysis. This offers not only opportunities to help engineers improve the safety and maintainability of critical structures but also new challenges which required further advances in fundamental research and applied technologies. On the other hand, wide technical possibilities are opened by the design of new metamaterials in sound and vibration control, biomechanics, nanotechnology, and extreme mechanics.

Based on the above considerations, we gathered together in 2016 and proposed this special issue which is aimed at serving a research milestone that summarizes the most recent progress in the field of metamaterials and smart structures.

To ensure the paper quality, rigorous reviews have been performed, and the final acceptance rate is around 40%. The 12 papers appearing in this special issue address a wealth of topics relevant to the proposed topics. This special issue discusses various materials including different characteristics and performances of 1D photonic crystals and the effect of nanosilica on the fresh properties of cement-based grouting material. It also discusses different structural damage detection methods, including musical tone law method by using vibration data, delamination detection based on laser ultrasonic imaging, bridge deflection monitoring using CCD cameras, and quick structural monitoring and damage assessment technique using smartphone. Further, it addresses the finite element computations of contact problems in micropolar elasticity, as well as vibration and acoustic emission tests on scaled structural models.
