Single-Course Danish 5 ECTS

Dimensioning and strength 1

Overall Course Objectives

Introduction to the fundamental concepts and methods of strength of materials. The student should be able to treat elementary problems in relation to the strength and deformations of machineries.

Learning Objectives

  • Analyse beam problems and identify appropriate solution procedures
  • Compute force components and bending moment components in beam structures.
  • Use the beam differential equation to calculate the deflection of beams.
  • Determine moments of inertia and bending stiffnesses for homogeneous and composite beams.
  • Determine stresses and strains in homogeneous and composite beams.
  • Solve statically in-determined beam problems by using superposition of standard solutions.
  • Determine stresses and deformations in torsion of bars with circular cross section.
  • Dimensioning of beams, columns and shafts in ordinary mechanical designs by e.g. use of standards.
  • Explain the limitations for simple beam theory.
