Single-Course Danish 5 ECTS

Strength of materials 1

Overall Course Objectives

To introduce the basic concepts and methods of strength of materials. To enable the student to deal with elementary problems concerning strength of structures.

Learning Objectives

  • Use statics to determine reactions and forces in structures.
  • Calculate bending moments, shear forces and normal forces in beams by the use of free body diagrams.
  • Determine the stress distributions in beams, including maxima and minima.
  • Use the beam differential equation to compute deflections.
  • Solve beam- and frame problems, statically determinate or indeterminate, by using elementary beam solutions and the superposition principle.
  • Calculate stresses and deflections in composite beams.
  • Determine the moment of inertia and the bending stiffness for homogeneous beams and for composite beams.
  • Use Euler columns in the dimensioning of structures.
  • Calculate stresses and deformations in torsion of round bars.
  • Determine shear stresses on the cross-sections of beams.
