Solid Mechanics, Basic Course

Main field: Technology.

Compulsory for: F2

Elective for: Pi4, Pi4-bs

Language of instruction: The course will be given in Swedish

The aim of the course is to give the basic knowledge of solid mechanics with applications to everyday engineering problems.

Knowledge and understanding

For a passing grade the student must

- be able to explain and use the concepts of stress and strain
- understand the importance of modelling the mechanical properties of the material to describe the relation between stress and strain
- be able to describe the phenomena principle stresses and principle strains
- be able to explain what happens in form of plasticity or fracture by overload

Competences and skills

For a passing grade the student must

- be able to identify what loads a structure is subjected to
- be able to calculate the deformations and stresses caused by these loads
- be able to calculate when fracture occurs in a structure

Judgement and approach

For a passing grade the student must

- be able to estimate the risk of permanent deformations or fractures in the structure

The following subjects are dealt with in the course: Stress and strain analyses, mainly the state of plain stress. The three simple loadcases; uniaxial traction force, torque and bending moments applied to straight bars. Statically indeterminate beams. Fatigue. Rheological models.

Grading scale: TH

Assessment: Written examination at the end of the course.

Required prior knowledge: FMA430 Calculus in Several Variables, Basic courses in Engineering Mechanics.

The number of participants is limited to: No
