DOI: 10.1002/adfm.202420892
Abstract: Mechanical metamaterials have considerable application potential, but are often limited to single applications owing to material and manufacturing constraints. To achieve a “single structure, multiple applications” goal, this study presents a multifunctional metamaterial structure. The… read more here.

DOI: 10.1016/j.engfracmech.2018.07.009
Abstract: Abstract Fissured rocks, widely existing in underground engineering structures, are quite sensitive to coupled static-dynamic loading conditions. Understanding the mechanical properties of fissured rocks under coupled loads is significant for the rational design and stability… read more here.
