Intended learning outcomes

After completion of the course the participants are expected to be able to:

  • design sandwich beams and isotropic sandwich plates subjected to transverse loads and in-plane loads with respect to transverse displacement, strength, critical buckling load, natural frequencies and local buckling.
  • determine when sandwich structures are favourable with respect to other structural concepts
  • use optimisation methods, with and without constraints
  • formulate a structural problem as an optimisation problem, and solve it
  • discretise and perform finite element analysis of sandwich structures

Course main content

Fundamental beam theory for sandwich constructions. Plate theory (Reissner/Mindlin) for sandwich structures. Design considering failure criteria and finite element modelling of sandwich structures. Basic structural optimisation with applications in composite- and sandwich structures. Life cycle analysis, manufacturing and environmental aspects of sandwich structures. Compulsory elements include a hands-on laboration, and a programming- and design assignment.


Base programme BD, M, P, T or equivalent. SF1861 Optimization for T, SD2411 Lightweight Structures and FEM and SD2413 Fibre Composites – Analysis and Design are recommended.
