Aim

Provide knowledge about Strength of Materials concepts, methods, mechanisms and limitations, and the ability to formulate, and solve simpler Strength of Materials problems and assess the accuracy of the model and solution.

Learning outcomes (after completion of the course the student should be able to)

  • master the concepts of loads, deformations, strains (mechanical and thermal) and stresses
  • master constitutive relations for elastic materials and conditions for yielding (plastic deformation)
  • master the calculation of stresses and deformations in simpler design components such as bars, shafts, beams and pressure vessels (thin-walled and thick-walled)
  • master the formulation of compatibility conditions for trusses, axle systems and beam systems
  • master the concepts of principal stresses and effective stresses for general stress states
  • master the risk assessment for buckling in compressive loaded struts 
  • understand the risk of failure due to maximum stress, fatigue and instability
  • calculate stresses and deformations in plane elastic problems using the finite element method and MATLABs PDE toolbox.

Content

Constitutive (material) relations, kinematic relations (compatibility), and the equilibrium relations for bars, shafts and beams are treated in detail. Methods for determining the sectional force distribution in structures composed of such structural elements are described, and it shows how stresses can be determined (assuming given sectional forces). The structures can be loaded by external loads, temperature loads and internal forces. Elastic stability of axially loaded beams is reviewed. Further, general stress states is treated, in particular stresses in pressure vessels and thick-walled pipes. The concepts of principal stresses and effective stress are reviewed. An Introduction to stress concentrations, fatigue design and the finite element method is also included.

Organisation

Lectures, exercises, and tutorials (opportunities for teacherassisted self activity), some assignments.
