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 5,000 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.

Welcome to Reliability and Risk Analysis of Wind Turbines

 

Description: Reliability is a very important issue for wind turbines. Reliability is important both for estimating failure rates and probabilities for different components and members in structures, and for planning optimal operation and maintenance. In traditional deterministic code-based design the structural costs are influenced by the value of the safety factors. These reflect the uncertainty related to the design parameters. Improved design with a consistent reliability level for all components can be obtained by use of probabilistic reliability-based design methods, where explicit account of uncertainties related to loads, material strength, and calculation methods is made.

The course will include the following topics:

  • Introduction to risk and reliability analysis
  • Stochastic modeling of uncertainties and failure rates, incl. Bayesian techniques
  • Reliability analysis of electrical and mechanical components
  • Reliability analysis of structural members by FORM/SORM and simulation methods
  • Reliability assessment using theoretical models in combination with information from tests
  • Methods for reliability analysis of wind turbines

Prerequisites: Basic knowledge on probability theory and statistics.

Welcome to Detection and Quantification of Microplastic

 

Description: Microplastic occurs in surface waters, wastewaters, stormwaters, aquatic sediments, terrestrial soils, and biota living in these environments. In this course we cover

  • The state-of-art of microplastic in the environment
  • Methods to extract microplastic from environmental samples
  • Identification of microplastic using micro-FTIR imaging

The form of the course is partly theoretical and partly practical. Theoretical aspects are first in a combination of lectures and study groups. Practical aspects are addressed in small groups conducting practical exercises on microplastic extraction and identification.

Prior to the course the students have to acquaint themselves with selected literature and the course is evaluated based on a small report written on the work done during the course.

Description: The course concerns the physics and modelling of wave propagation in structures and solids. The theories and formulations covered by the course are applicable within structural and mechanical engineering as well as earthquake and geotechnical engineering. Firstly, an introduction is given to the basic properties of body waves in an elastic continuum. Phenomena such as geometrical and material dissipation, dispersion, impedance, reflection and refraction are discussed. Furthermore, the formulation of theories for wave propagation in one-dimensional structures, including straight and curved beams, plates and cylindrical shells, is considered. The Floquet theory for periodic structures is introduced and exemplified. Secondly, the finite element method is introduced as a computational tool for the analysis of wave propagation in soil and structures. Special attention is paid to its wave format for modelling one- and two-dimensional piecewise homogeneous/periodic structures. Time and frequency-domain solutions are considered, and guidelines are given for the treatment of artificial boundaries in numerical models. Thirdly, boundary integral equations and boundary-element schemes for wave propagation in solids and structures are derived in the frequency domain, and an alternative solution for stratified materials, e.g. layered soil, is given in the wavenumber-frequency domain. Finally, lumped-parameter models (LPMs) are introduced as a means of representing the dynamic stiffness of continuous structures and soil in a computationally efficient manner. As an example, the application of LPMs for wind-turbine or machine foundations is illustrated.

Prerequisites: The participant must have a solid background in continuum mechanics and partial differential equations. Experience with numerical methods and programming is strongly recommended. The participants are expected to read the texts in the literature list before the course. The literature will be available upon registration.

Form: Each part of the course consists of a lecture followed by a workshop. The lectures are given in English.

Evaluation: As part of the course work, the participant must hand in a portfolio containing answers to exercises as well as computer codes elaborated by the participant during and after the course. Some of this work may be carried out in the workshops.
