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 and constituent materials. 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 the modeling, simulation, and design theory/methodology, as well as enabled novel engineering applications across a wide range of length scales. Specific topics of interest include, but are not limited to:
• Modeling, simulation, and design theory/methodology for mechanical metamaterials at all scales 
• Topology optimization of single- and multiple-material mechanical metamaterials
• Mechanical metamaterials with novel properties and functionalities, such as unique acoustic properties, negative Poisson’s ratio, negative stiffness etc.
• Origami and Kirigami-based 2D and 3D deployable and expandable metamaterials
• Programmable and reprogrammable mechanical metamaterials
• Buckling-based reconfigurable metamaterials
• Stimuli-responsive active soft mechanical metamaterials
