Course notes / slides.

Teaching method

In theoretical classes, the subject is exposed, and student participation is encouraged.

In practical classes, laboratory tests are carried out that encourage contact with equipment and the acquisition of sensitivity for carrying out experimental work.

In addition to face-to-face contact classes, tutorial monitoring of students is carried out supported by online teaching-learning tools.

Evaluation method

Option 1:

1st Test on NDT (35%);

2nd Test on ED (35%);

Report of on-site visits to the Laboratories (30%).


Option 2:

Exam (100%)

Subject matter

Part 1: Destructive Testing (DT)
- Materials, Material Groups, Properties, Concepts and essential phenomena;

- Essentials of the main Destructive Tests:
1) Uniaxial Tensile Testing (UTS)
2) Uniaxial Compression Test (UTS)
3) Bend Test (3 and 4 points) and Bending
4) Torsion Test
5) Hardness Testing (Brinell, Rockwell, Vickers, Knoop)
6) Impact Test (Charpy)
7) Biaxial test (Erichsen, Nakajima)
8) Fatigue Test
9) Creep test


Part 2: Non Destructive Testing (NDT)

- Background, Generalities, Reliability, Industrial applications;

- Defects (Morphology, location and dimension) and relation with Materials+Processes;

- NDT Methods and their Techniques (Fundamentals, Applications, Technological aspects):
1) Visual Inspection (IV)
2) Liquid Penetrant (LP)
3) Magnetic Particles (MP)
4) Radiology (RX)
5) Ultrasound (US)
6) Induced Currents (IC)
