Mechanical metamaterials are becoming an emerging frontier in scientific research and engineering innovation due to their unprecedented physical properties, arising from the innovative geometrical design of unit cells. Meanwhile, when in response to different stimuli, mechanical metamaterials can be reconfigured beyond their original designs by reversibly changing the size, shape, and symmetry via simple deformation, offering enhanced flexibility in performance and tunable properties coupled with dynamically changing structural configurations. Mechanical metamaterials synergistically integrate mechanics, geometry, design, properties, and manufacturing. This symposium will represent the emerging and recent advances in mechanical metamaterials with a focus on their extraordinary mechanical behaviors through purposeful geometrical and mechanical designs, as well as enabled novel engineering applications across a wide range of length scales. Topics of particular interest include:

• Modeling, simulation, fabrication, and experimental characterization of mechanical metamaterials at all scales

• Manufacturing of metamaterials in polymers, metals, ceramics, and combinations

• Design of architectured metamaterials for unique mechanical properties

• Origami and Kirigami-based 2D and 3D deployable and expandable metamaterials

• Programmable and reprogrammable mechanical metamaterials

• Buckling-based reconfigurable metamaterials

• Design of unit geometry and hierarchical structure for unprecedented mechanical and acoustic properties (e.g. negative Poisson’s ratio, negative stiffness, negative acoustic indices etc) • Stimuli-responsive active soft mechanical metamaterials

• Multifunctional mechanical metamaterials in mechanics, acoustics, electronics, medicine, and reconfigurable soft machines etc.
