Biology involves inherently complex three‐dimensional designs. In addition to the geometric complexity, thin and complex biostructures composed of membranes such as insects, wings, and plants leaves can achieve complex functionalities under vibrations, such as maneuverability and resistance to strong winds, respectively. They do so by changing the shape and curvature of their membranes and ribbons...
In article number 1703852, Andreas A. Polycarpou and co‐workers fabricate and study the deformation of three‐dimensional (3D) multilayered Kirigami microstructures with potential applications in 3D microelectromechanical systems (MEMS) devices. The mechanical response under flat‐punch compression is studied using combined experiments and finite element analyses. The findings reveal different geometry‐dependent...
Mechanically guided 3D microassembly with controlled compressive buckling represents a promising emerging route to 3D mesostructures in a broad range of advanced materials, including single‐crystalline silicon (Si), of direct relevance to microelectronic devices. During practical applications, the assembled 3D mesostructures and microdevices usually undergo external mechanical loading such as out‐of‐plane...
The mechanical behavior of nano-scale metallic glasses was investigated by in situ compression tests in a scanning electron microscope. Platinum-based metallic glass nano-pillars were fabricated by thermoplastic forming. The nano-pillars and corresponding bulk substrate were tested in compression over the range of room temperature to glass transition. Stress–strain curves of the nano-pillars were...
