Description of the Workshop
Over the last few decades, the scientific community has witnessed rapid progress in material manufacturing and computational capabilities. Focusing on the basic premise of such recent advancements in additive manufacturing, computing and artificial intelligence, a new research domain on engineered materials has emerged. The mechanical attributes in these materials can be tailored to specific engineering demands leading to extreme and unusual (normally not achievable in conventional naturally occurring materials), yet useful properties, resulting in a range of benefits for various multi-functional systems. This new class of materials is increasingly being adopted in multiple advanced industrial structures and mechanical systems. The primary objective of this course is to disseminate the core concepts of engineered materials (focusing on mechanical metamaterials at micro and nano scales) including their current and prospective applications. A broad overview will be given initially on the mechanical properties of conventional materials, and subsequently, the participants will be exposed to the more advanced domain of “materials by design”, involving multi-disciplinary topics such as mechanics of mechanical metamaterials, finite element analysis, molecular dynamics simulations, artificial intelligence and machine learning, topology optimization. Emphasis will be placed on the concepts of multiscale bridging through exploiting machine learning along with the aforementioned physics-based simulation approaches. Two appropriate hands-on tutorials will be provided in an order of increasing complexity and involving two different length scales with the aim of identifying multi-functional material configurations.
