Teaching language

Suitable for English-speaking students

Objectives

Specific aims:
Learning the main experimental methods and techniques used in the analysis and monitoring the behaviour of structures and components.

At the end of the first trimester,
Students should be acquainted with the main procedures, which are necessary to measure structures and interpret results.

At the end of the semester,
Students should be capable of distinguishing the different measurement techniques regarding their way of measurement and resolution. Every time they come across with a monitoring problem, they should know which technique should be selected.

Learning outcomes and competences

It is expected that students gain experience in contact with real engineering problems requiring experimentation. Students should also learn  how to use the main experimental techniques available.

Working method

Presencial

Pre-requirements (prior knowledge) and co-requirements (common knowledge)

Solid Mechanics, Statics and Instrumentation

Program

Brief revision of the characteristic of state of stress at a point; displacement and deformation fields; Hooke’s law and deformation matrix; Obtaining a stress matrix.
Classic techniques of obtaining stress at a point; mechanical and electrical extensometry; Geometrical Moiré techniques varnish method.
Introduction to the study of light; Light sources, continuous/pulsed emission, polarization, bandwidth, spatial/temporal coherence; Measurement of stress/deformation with photo elasticity; Coherent radiation and speckle generation; Holographic register and holographic interferometry; Techniques of image processing applied to experimental mechanics.

Instrumentation: transducers and measurement systems; Acquisition system and data processing at one, two and three dimensions; Telemetry systems and data storage systems; image techniques applied to the structure behaviour.

The study of the techniques presented will be complemented by the presentation and discussion of different applications at LOME (Laboratory of Optics and Experimental Mechanics) of DEMEGI/INEGI.

Students will have the chance to do group assignments about the application of techniques.

Eligibility for exams

Registration + attendance to classes >75% of theoretical-practical classes + final test + practical assignment

Calculation formula of final grade

Final Exam = (55% of the final grade)
Practical assignment = (45% of the final grade)

Comment: the assessment of the practical assignment will cover the report, results and presentation.

Special assessment (TE, DA, ...)

According to the internal rules of FEUP

Observations

Students should have completed the following course units: Mechanics I, Mechanics II and Solid Mechanics.
