Welcome to Vibration-based Structural Health Monitoring

Description: 
The aim of this course is to give the participants an insight into the use of vibration measurements to assess the integrity of structural systems and components. This procedure is referred to as vibration-based structural health monitoring (SHM), which is of interest within several engineering disciplines; including energy, civil, mechanical, and aerospace. Here, SHM can be used as a key component in optimization of operation and maintenance procedures.                          


In the course, we will address the following topics:

  • Structural damages, their appearance in engineering structures, and potential consequences
  • Theoretical, numerical, and experimental deterministic and stochastic vibration analysis
  • Deciding on the spatial distribution of sensors for capturing vibration signatures
  • Signal processing of vibration signatures for discrimination between damage-induced anomalies and environmental and/or operational variability
  • Characterization of structural damages using signal-processed vibration signatures
  • Industrial perspectives and real-life application examples

The course consists of lectures, solving theoretical exercises, and conducting experimental studies to increase the physical understanding of the theory. The target audience is PhD students within energy, civil, and mechanical engineering or similar, but young researchers and professionals from the industry with an interest in the topics of the course are also welcome.       

An assignment will be given as homework. Satisfactory answers to the homework are a prerequisite for passing the course.

Important information concerning PhD courses: We have over some time experienced problems with no-show for both project and general courses. It has now reached a point where we are forced to take action. Therefore, the Doctoral School has decided to introduce a no-show fee of DKK 3,000 for each course where the student does not show up. Cancellations are accepted no later than 2 weeks before start of the course. Registered illness is of course an acceptable reason for not showing up on those days. Furthermore, all courses open for registration approximately three months before start. This can hopefully also provide new students a chance to register for courses during the year. We look forward to your registrations.

Prerequisites:

  • Master degree in Engineering or similar
  • Basic knowledge on calculus and linear algebra, as obtained through engineering studies
  • Basic knowledge on MATLAB or any other programming language
  • Basic knowledge on structural mechanics and dynamics.
