Steel structures

Objectives / Skills acquired
Metal assembly
In this course, the assembly methods used to create permanent connections (riveting, welding, bolting, gluing) will be presented. The aim is to present the principles of force transmission, design and pre-dimensioning rules for these connections, as well as implementation techniques. Particular emphasis will be placed on the assembly techniques used in repair work for patching, doubling, splicing, etc. This course is specifically geared towards metal structures, but will be a prerequisite for introducing assembly techniques for composite and/or multi-material structures
Metallurgy: Corrosion
The aim is to make students aware of the corrosion problems encountered in aeronautics. The course will also present techniques used in research laboratories to characterize a material's behavior in the face of corrosion
