The aim of this course is to introduce the techniques and possibilities in classical and modern experimental mechanics for the characterization of the mechanical behaviour of solid, porous and fibrous materials, as well as and additively manufactured materials with a designed structure. After competed course the student should be able to:
assess suitable characterization method for specific application areas, depending on which engineering properties are of relevance,
critically assess the error sources and in experimental test methods and their implications in design,
explain emerging full-field test methods, and how inverse modelling can be used to identify key material parameter,
perform laboratory experiments, collect and analyze data in order to determine material properties.
As basics, the classical methods for characterization of mechanical properties of load-carrying materials will be covered: Specimen preparation, measurement of load, deformation and strain, test methods in tension, compression, shear, bending, crack propagation in quasi-static condition and with time dependence. Quantitative analysis of the influence of machine compliance on measurements, including uncertainty analysis. Modern full field analyses using digital-image/volume correlation, including inverse analysis for parameter identification.
Lectures, seminars, a project consisting of consecutive laboratory exercises carried out in student groups.
Written exam at the end of the course (3 credits), and laboratory assignments with written report (2 credits).
If there are special reasons, the examiner may make an exception from the specified examination method and allow an individual student to be examined in another way. An example of special reasons might be a certificate regarding special pedagogical support from the University's disability coordinator.
