TMHL03 Mechanics of Light Structures, 6 ECTS-points
/Hållfasthetslära; Lätta konstruktioner/

Advancement level:
C

Aim:
In this course the general three dimensional field equations of elastostatics are specialised in different ways in order to obtain various simplified theories valid for special cases of loading and geometry. This serves the twofold purpose of deriving theories useful in engineering practice, such as Kirchhoff plate theory and achieving familiarity with the general three dimensional equations. Finally, a qualitatiave discussion about composites in general, and the use of such in thin-walled strucutres will be given.
