FHLN25, 7,5 credits, A (Second Cycle)

Valid for: 2017/18
Decided by: PLED M
Date of Decision: 2017-04-05

General Information

Elective for: BME4, F4, M4-bem, Pi4
Language of instruction: The course will be given in English


The purpose of the education is to provide the need for fracture mechanical competence to judge risk for failure and to compute stiffness reductions due to cracks. The aim is that the student should gain knowledge of linear and non-linear fracture mechanics and to serve as an industrial resource with the ability to analyze failures, suggest models for calculation and suggest structural improvement of engineering structures.

Examination details

Grading scale: TH - (U,3,4,5) - (Fail, Three, Four, Five)
Assessment: Written examination. In the case of less than 21 registered students the examination may be given in oral form.

The examiner, in consultation with Disability Support Services, may deviate from the regular form of examination in order to provide a permanently disabled student with a form of examination equivalent to that of a student without a disability.


Required prior knowledge: Solid Mechanics (FHLF15 or FHLA10) and Finite Element Method (FHLF20, FHLF01 or FHLF10) and Computational Inelasticity (FHLN05) or equivalent courses.
The number of participants is limited to: No
The course might be cancelled: If the number of applicants is less than 16.
