Course content

Simple statically indeterminate systems. Shear stress and shear strain. Shear stresses in beams. Torsion. Stresses in cylindrical and spherical vessels and pipes. 2D and 3D stress state. Hooke's law. Principal stresses and strains. Yield criteria from Tresca and Mises. Unsymmetrical cross-sections. Composite beams. Buckling of columns and beams.

Learning outcome

The two basic courses Mechanics 1 and Mechanics 2 provide a basic knowledge of statics and strength of materials. The courses are compulsory for study programs MTBYGG, MTING, MTMART and MTPROD. The two courses form a foundation for advanced topics in solid mechanics at these study programs.

Mechanics 2 has the following learning objectives:

Knowledge:

The candidate should have knowledge of:

- The difference between statically determinate and indeterminate structures

- Definition of shear stress, shear strain and shear modulus

- Source and distribution of shear stresses in beams

- Source and distribution of stresses in thin-walled pipes and containers

- Transformation of stresses and strains between different reference systems

- Plan stress and strain conditions

- Isotropic yield criteria (Tresca and Mises)

– Beams with unsymmetrical cross-sections

– Stresses in composite beams

- Phenomenology and mathematical treatment of buckling

Skills:

The candidate is able to:

- Determine the forces and deformations in simple statically indeterminate system

- Calculate the shear stresses caused by V

- Calculate stresses in thin-walled pipes and containers

- Transforming stresses and strains, including determining the principal stresses

– Calculate stresses in unsymmetrical cross-sections and in composite beams

- Calculate the elastic buckling load

- Apply Python as a tool in analysis of problems in mechanics

General competence:

The candidate can:

- Explain the basic principles of mechanics of materials

- Perform simple calculations by hand and with Python in the framework of the syllabus of the course

Learning methods and activities

Lectures, calculation exercises and laboratory exercise. Python or Matlab is applied in some exercise problems. Access to the exam requires that the laboratory exercise and 2/3 of the calculation exercises have to be approved.

Compulsory assignments

• Exercises

Further on evaluation

If there is a re-sit exam, the examination form may be changed from written to oral.
