About this Research Topic
Recently, supported by advanced manufacturing such as 4D printing, active metamaterials have demonstrated excellent functionalities and tunable properties due to their adaptable capability to change shape in a programmable, untethered, and reversible manner, showing potential applications in soft robots, actuators, shape morphing structures, intelligent biomedical devices, thermal engineering devices, tunable physical properties, elastic wave control, and acoustics. Combining structural mechanics and functional materials, one can reconfigure structures mainly controllable by heat, fluid, light, magnetic field, external force, and other external stimuli.
This research topic aims to disseminate novel research findings in mechanical metamaterials.
We invite two paper types – i) original research or ii) review, on the fundamental studies on mechanical metamaterials' mechanics and design and their engineering applications across various scales. Examples of topics include (but are not limited to):
• Metamaterials with negative Poisson's ratio, negative thermal expansion, negative stiff-ness, negative compressibility, and other tunable properties
• Analytical, numerical, and experimental studies on the behaviors of architected structures, lattice materials, foams, granular structures, origami, kirigami, and tensegrities
• Mechanics and design of reconfigurability, tunability, multi-stability, symmetry breaking, coupling effects, and other interesting functional properties of mechanical metamaterials
• Advanced technologies such as 3D/4D printing to manufacture mechanical metamaterials.
• Active metamaterials deformable by external stimuli.
