Selection

The selection is based on 20-285 credits

Course Aim
The aim of the course is that the student should be able to
• calculate critical load (instability) according to first and second order theories for 1-dimensional and 2-dimensional trusses and frames
• calculate deformations and stresses in slabs, plates and shells
• calculate shear forces and stresses of torsion of non-circular cross-sections
• plan and perform calculation tasks, process results and present them in writing (calculation report)

Contents
Critical load (instability) for 1-dimensional elements
• according to first order theory
• with the influence of transverse forces
• stiffness matrix and load vector
• deriving Euler's buckling cases

Critical load (instability) for 2-dimensional trusses and frames
• according to first and second order theories
• stiffness matrix and load vector
• condensation of stiffness matrix and load vector
• criteria for instability

Deformations and stresses in
• plates
o plane stress and plane strain conditions
o Airy’s stress function
o boundary conditions
o symmetrical stress distributions
o linear load on half space
o holes
• slabs
o Kirschoff’s slab theory
o Reissner’s slab theory
o energy equations
• shells
o spherical shells
o single curved shells

Section forces and stresses of torsion for statically determinate and indeterminate elements with non-circular cross-sections
• without prevented warping
o Saint-Venant’s theory
o thin-walled closed cross-sections
• with prevented warping
• shear centre and torsion centre

Realization
Each course occasion´s language and form is stated and appear on the course page on Luleå University of Technology's website.
The students participate in lectures where backgrounds and theories to the course content are derived, presented and exemplified.

The students practice calculation methodology and theories for the course content
• individually partly in practice sessions in classrooms for simpler structures, partly in the computer room in assignments
• in a group for larger structures in project tasks

Students practice the ability to plan, implement and report calculation tasks individually in assignments and in groups in project assignments.

Examination
If there is a decision on special educational support, in accordance with the Guideline Student's rights and obligations at Luleå University of Technology, an adapted or alternative form of examination can be provided.
Background, theories and calculation methodology for simpler structures (a few elements) are examined with a written final exam. Grading scale: U, 3, 4, 5.

Calculation methodology for larger structures is examined through written calculation reports of assignments and project assignments. Grading scale: U, G
