Content and learning outcomes
Course contents
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.
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

Examination and completion
If the course is discontinued, students may request to be examined during the following two academic years.
Grading scale
A, B, C, D, E, FX, F
Examination

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.
The examiner may apply another examination format when re-examining individual students.
Other requirements for final grade
Assignment (LAB; 3 university credits) and written exam (TEN; 3 university credits).
Opportunity to complete the requirements via supplementary examination

Ethical approach
- All members of a group are responsible for the group's work.
- In any assessment, every student shall honestly disclose any help received and sources used.
- In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
