SOLID MECHANICS, BASIC COURSE | FHL105 |

**Aim**

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

*Skills and abilities*

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

**Contents**

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.
