In this course, we will see how architectured materials combining mechanical, acoustic, thermal, and electromagnetic properties can be designed through a clever interplay of materials and careful choice of geometries.
Choosing Materials and Processes: The Art of Compromise
The lecture will cover various digital simulation methods, but also the virtues of simplified analytical approaches, illustrated by fundamental questions of physical metallurgy such as hardening and precipitation.
The issue of materials durability is central to both the aerospace (engines) and nuclear sectors. The key issue is the reliability of accelerated testing, and its use in predicting the materials’ lifespan. These concepts are illustrated in the field of creep, fatigue and corrosion.
Hierarchized Architectures: Lessons of the Living World
This lecture will draw a parallel between engineering designs and natural solutions. Nature functions at fairly low temperatures, and is restricted to organic materials or solutions chemistry: its fascinating variety of materials comes from the variety of natural hierarchical architectures that can be observed in wood, bones or shells. Conversely, engineers have access to a wide selection of building blocks, but remain not very inventive in terms of architectures. The combination of these two strategies, which forms the basis of structural biomimetism, may turn out to be a considerable source of innovation.
