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.

Teaching methods

Explanations at the blackboard. Practical exercitations and training in the Lab.

Assessment methods

Student assessment is performed by a written test, consisting of three questions. They may have a theoretical or a practical content, with reference to the main Course topics.

Teaching tools

Blackboard.

Practical training in the University Lab on: Strain gauges, Photoelasticity, Non-Destructive Control Techniques.
