Abstract Scope |
Architected cellular structures are oftentimes known for their superior mechanical properties such as high strength-to-weight ratio and damage tolerance. The mechanical properties of architected cellular materials are governed by their base materials and multi-scale hierarchical structures. We will first present novel computational approaches based on advanced optimization algorithms and machine learning techniques to design architected cellular materials at multiple length scales, from several nanometers to centimeters. Additive manufacturing (AM) is a promising technology to create architected cellular materials with complex structures. However, current AM techniques are not robust when it comes to defects. In the second part of this talk, we will discuss how to improve the printing quality of AM by incorporating sensor technologies and machine learning algorithms to adaptively adjust process parameters in real-time. This framework will ultimately lead to the discovery of highly versatile metamaterials, opening up unexplored possibilities in the field of materials design and manufacturing. |
