We study the propagation of a bridge crack in an anisotropic multi-scale system involving two discrete elastic chains that are interconnected by links and possess periodically distributed inertia. The bridge crack is represented by the destruction of... Read More about Dynamic fracture regimes for initially prestressed elastic chains..

A gyro-elastic device for cloaking of elastic waves in micro-structured materials (2019)
Conference Proceeding
Garau, M., Nieves, M., Carta, G., & Brun, M. (2019). A gyro-elastic device for cloaking of elastic waves in micro-structured materials. . https://doi.org/10.1109/MetaMaterials.2019.8900841

The design of a structured gyro-elastic system capable of being used as a cloaking device for a discrete medium is discussed. The efficiency of the gyro-elastic cloak, composed of springs connecting periodically placed masses, attached to gyroscopic...

For the first time, a design of a “deflecting elastic prism” is proposed and implemented for waves in a chiral medium. A novel model of an elastic lattice connected to a non-uniform system of gyroscopic spinners is designed to create a unidirectional...
