Before choosing course

Administrate About course

The course gives the basic knowledge in finite element methods for solving geometrically non-linear problems.

The course covers the following:

  • geometrical non-linear 2D bars, 2D beams and plane elements
  • different strain and stress measures
  • incremental solutions and convergence criteria
  • path following procedures
  • linearised and non-linear stability analyses
Course offering missing for current semester as well as for previous and coming semesters
* Retrieved from Course syllabus SG2870 (Autumn 2007–)

Content and learning outcomes

Course contents

  • Geometrical non-linear 2D bars, 2D beams and plane elements
  • Different strains and stresses
  • Total and updated lagrangian formulations.
  • von Mises plasticity in one and two dimensions for beam and plane elements
  • Incremental solutions and convergence criteria
  • Path following procedures

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

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

  • TEN1 - Examination, 4,0 hp, betygsskala: A, B, C, D, E, FX, 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)

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.
