Symposium Technical Description

Architectured meta-materials represent an emerging and exciting class of materials. These materials are characterized by specific and periodic structural features which are larger than what is typically considered microstructure (i.e. grains) or microstructural length scale but smaller than the size of the final component made of the architectured material. It is the structural features rather than the chemical composition or small scale microstructure that leads to their potentially extreme and multifunctional properties. The hierarchical, ordered, topologically complex nature of their structural architectures and the degree of precision with which such features can now be defined suggests the mechanical properties can now be designed and optimized not constrained by their inherent material composition. This class of materials includes but is not limited to lattice materials and cellular materials, dense materials composed of building blocks of well-defined size and shape. In architectured materials morphological control is high, which enables a tight control over mechanisms of local stress transfer, such as elastic/plastic buckling, gliding of building blocks or propagation of cracks. The result are efficient multi-scale materials with unprecedented ranges of density, stiffness, strength, fracture toughness, energy absorption, fatigue resistance, elasticity and ductility. Well-designed architectured materials can therefore generate new and attractive combinations of properties which can be programmed in the material and which are unattainable in monolithic materials. This symposium will cover research on the structure, mechanics, design, fabrication and mechanical performance of all categories of architectured materials including but not limited to lattice materials, metamaterials and topologically interlocked materials, as well as applications in fields such as automotive, aerospace, medical and energy engineering. The organizers will also host special discussion session to discuss the current research challenges challenges in the field of architected materials.
