Weight reduction is a key factor in many engineering applications especially for those ones interacting with the environment where future solutions will strategically require high strength/weight ratios.
For this reason, multidisciplinary approaches are needed to satisfy the stringent requirements of reliability, failure prevention, mass reduction and global optimization of performances.
The main focus of the course is on lattice structures made with metals from additive manufacturing. The course includes a survey on the main design and fabrication principles of lightweight structures: basic design methods, experimental methods and testing, manufacturing. Engineering solutions from real applications are explored and analyzed, focusing on their benefits, drawbacks, improvements and technical challenges.
Many disciplines are involved in the development of the tools usable for designing, validating and producing lightweight structures: structural mechanics, materials and manufacturing engineering, mathematics and others. Similarly, many tools are available to improve the design, such as finite elements methods (FEM), design for experiments (DOE), artificial intelligence (AI) algorithms for topology/shape optimization, etc. The final goal of the course is to provide a global view on lightweight structures and on the skills and tools suitable to their production.
