SE2152 Mechanics of Fiber Networks and Materials 8.0 credits

Fibre materials are an essential component of design. Working as an engineer, you will deal with various types of materials. Despite being simple in use, paper constitutes one of the most complex materials among those you encounter in your daily life. Paper can be easily tested mechanically and exhibits a whole range of behaviours during its end use. Therefore, studying the mechanics of fibre networks is an excellent opportunity to train your skills in analysing various aspects of mechanical behaviour of materials.

Intended learning outcomes

After the course, the students should be able to

  • describe and analyse important paper technology applications using correct solid mechanics terminology,
  • relate the results from the most important methods for mechanical testing of paper and board to the appropriate solid mechanics terminology,
  • describe important aspects of the constitutive modelling of paper and board for analyses of converting and end-use applications,
  • demonstrate the benefits of mathematical modelling and numerical analyses in paper technology applications,
  • discuss and argue for experimental and numerical results orally and in writing, and
  • appreciate the advantages, disadvantages and limitations of using paper as a renewable material.

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


  • HEM1 - Home assignments, 2.0 credits, grading scale: P, F
  • LAB1 - Laboratory work, 2.0 credits, grading scale: P, F
  • TEN1 - Examination, 4.0 credits, grading scale: 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.

The examiner, in consultation with KTH's coordinator for disabled students (Funka), decides whether an alternative examination suitable for course participants with a documented permanent impairment is possible. The examiner may allow an alternative examination form for re-examination of single course participants.

Other requirements for final grade

Approved Home assignments, Laboratory and Written examination.

Opportunity to complete the requirements via supplementary examination

No information inserted

Opportunity to raise an approved grade via renewed 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.
