Master's programme Polymer Engineering and Science (PES) 2025W |
| Learning Outcomes |
Competences |
| Students know and understand the methods for design and sizing weight efficient components for load-carrying structures used in e.g. aerospace and automotive applications. They are able to derive and apply advanced analysis and design methods for thin-walled structures with respect to strength, stiffness and stability requirements.

| Skills |
Knowledge |
Students are able to
- represent and analyze plane stress states of thin-walled structures by means of Mohr's circle (k3),
- consider non-linear material behavior and analyze residual stress states after plasticization (k3),
- analyze and design beam structures (profiles) with thin-walled cross-sections (skew bending, shear center, torsion, Bredt’s formulas, k4)
- analyze and design shear-field beams, shear-field systems, and box structures (k3),
- analyze and evaluate the onset of buckling of columns, plates and shells under compression and shear (k4),
- analyze and evaluate the load-carrying capacity of buckled plates (post-buckling analysis, k5),
- derive the ABD-matrix of anisotropic plates and explain strength analyses concepts for composites and sandwich materials, k3),
- present the concept of stress models and integrated computational tools for global light-weight structure analysis (k2).
