Content and learning outcomes
Course contents
Intended learning outcomes
After the course, students should be able to
- derive basic non-linear 2D bars, 2D beams and plane elements using the total and updated lagrangian formulations.
- implement von Mises plasticity in one and two dimensions for beam and plane elements.
- implement displacements and arc-length path following procedures
- use the commercial fem package ANSYS to analyse non-linear problems

Grading scale
Examination
- TEN1 - Examination, 4.0 credits, grading scale: A, B, C, D, E, FX, F
- ÖVN1 - Assignments, 3.0 credits, grading scale: P, F
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
Oral examination (TEN1, 4 university credits).
Exercises (ÖVN1, 3 university credits)
Opportunity to complete the requirements via supplementary examination
Opportunity to raise an approved grade via renewed examination
Examiner
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.
