Course content

The subject covers the basic topics and applications of No-destructive Techniques which can be used in the laboratory or in the field for structural health monitoring. The fundamental concepts include:
Theoretical resume which is the introduction and the basics of the course where main concepts as fields, waves (elastic and electro magnetic wave propagation), particles as well as sensors and measuring principles are presented.

Emphasis through all the course will be placed on the material sensitivity to climate parameters, for example to the mechanisms of Temperature-induced deterioration or air-surface interaction in the case of relative humidity.
Significant attention is given on how to conduct structural health monitoring in practice, looking specifically at the most important and used no destructive methods.

Each single method will be presented through the explanation of the basic principles on which it is funded, the inspection challenges that the method brings with it and its inspection reliability. In addition, important information will be given on what are the useful parameters to know to select the correct no-destructive technique on the base of the object/material to monitor or on inspection challenges that the expert has to face.
Some of the no-destructive techniques presented will be: ultrasonic, acoustic emission, microwave band inspection, Infrared thermography and optical interferometry.
As much as possible, and depending on the number of students, high priority is given to the use of the laboratory (and teaching in the laboratory), aiming to show the students how these methods work in practice. Reports and presentations from the use of these techniques - in small experiments on health monitoring of different materials and objects - will constitute 25% and exercise 10% of the final mark.

Learning outcome

Knowledge:
Knowledge about fundamental theories on propagation of elastic and electromagnetic waves on materials.
Understanding for the application of structural health monitoring in practical applications in the laboratory and in the field.
Detailed knowledge on the most used no-destructive techniques as infrared camera, acoustic emission, microwave band inspection, ultrasonics,….

Skills:
Ability to select the most appropriate no destructive technique based on the type of material or object to be monitored.
Ability to understand the material sensitivity to climate parameters, as mechanisms of Temperature- and Relative Humidity- induced deterioration.
Perform structural health monitoring in the laboratory and in the field.

General competence:
General competence within fundamental and applied physics on structural health monitoring.
Good background for performing monitoring campaigns in situ.

Learning methods and activities

lectures, execises and trial lectures in the laboratory will be the main teaching methods and activities. The students, on their side, will conduct – as test - short experiments on health monitoring on different materials and objects using the most important no-destructive techniques presented at lessons. The lectures and exercises are in English as well as the Examination papers. In this case the students also have to reply in English.

Further on evaluation

Portfolio assessment is the basis for the grade in the course.
The portfolio includes a final written exam (65%), compulsory experimental works (25%) and exercises (10%).

The results for the parts are given in %-scores, while the entire portfolio is assigned a letter grade.

If there is a re-sit examination, the examination form may be changed from written to oral. For a re-take of an examination, all assessments during the course must be re-taken.
