Lattice and other discrete models have always been extremely popular tools in understanding molecular models in physics, chemistry and biology. Recently they played a prominent role in the development of next-generation materials such as metamaterials. These structures provide deeper insight into the influence of microstructure on dynamic processes in solids and are easily tunable for different design purposes. Consequently, this has been exploited to produce materials capable of counter-intuitive effects such as focusing, negative refraction and cloaking, to name only a few. The applicability of such models continues to widen, with more recent applications appearing in civil engineering, manufacturing, the nuclear and electrical industries, and healthcare.
Wave propagation in structured media can lead, however, to unfeasible deformations, producing the initiation and propagation of failure. The latter, coupled with dynamic phenomena, presents an important and challenging problem. The subsequent study can reveal important information about the structure’s influence on failure and phase transition processes, which includes associated propagation regimes.
The intention of this minisymposium is to bring together established world-class experts with a newer generation of researchers working in the dynamic failure in structured materials. Some topics in this minisymposium, which will stimulate professional discussions and potential future collaborations, include
• General dynamic effects in structured materials,
• Various lattices with defects,
• Wave transmission and localization,
• Dynamic phase transition and non-equilibrium materials,
• Ordered regimes of lattice dynamic transformation,
• Catastrophic failure and fracture propagation,
• Slow dynamic processes, fatigue.
