The course provides an introduction to experimental mechanics and covers basic and advanced solid mechanics experimental testing methods. The basic working principles of analogic transducers, testing machines and of optical and X-ray tomographic imaging techniques are illustrated along with an overview of the essential image processing and analysis approaches. ccc
Learning objective
Understanding the basic principles of experimental methods in solid mechanics and acquiring the ability to properly design, execute and analyze experimental tests targeted to investigate a mechanical process.
Content
1. Introduction: testing machines; analogic and digital signals; force, displacement and strain transducers; test control. 2. Analogic transducers: working principles; load cells; LVDTs; strain gauges. 3. Solid mechanics tests: compression, tensile and bending tests; fracture mechanics tests. 4. Optical methods: 2D and 3D digital image correlation, basic principles and applications. 5. 3D X-ray computed tomography (CT): basic principles; CT scanning; image reconstruction and artifacts correction; segmentation, filtering and analysis. 6. Overview of advanced topics: 4D X-ray CT; in-situ testing; digital volume correlation; laser speckle interferometry; dynamic testing and high-speed cameras.
