Learning outcomes
The first aim of this course is to present a complete review of the failure mechanisms of materials. A further aim is to introduce the main methods for experimental stress analysis and for non-destructive tests.
Course contents
Experimental stress analysis by strain gauges and photoelasticity.
Low-cycle fatigue: cyclic hardening or softening, the cyclic curve, the hysteresis curve.
Non-destructive test methods: Penetrant liquids, Magnetic particles, Eddy Currents, Ultrasound inspection.
Specific Lab exercitations on: strain gauges, photoelasticity, dye penetrants, magnetic particles, eddy currents and ultrasound inspection.
Readings/Bibliography

Teaching methods
Explanations by notes on a tablet. Practical exercitations and training in the Lab.
Assessment methods
Student assessment is performed by a written test, consisting of four questions. They may have a theoretical or a practical content, with reference to the main Course topics (including as well those of lab practical exercitations).
Teaching tools
Slide projector. A tablet used as "virtual blackboard". Copies will be provided (by publication on virtuale.unibo.it) at the end of the lectures.
Practical training in the University Lab on: Strain gauges, Photoelasticity, Non-Destructive Control Techniques.
