The course represents an overview of current experimental methods and procedures in the following fields:

- experimental analysis of the main mechanical quantities (stress, displacement, force, torque, pressure, etc.),

- experimental dynamics (shakers, vibration transducers, damping, balancing, vibroanalysis).

Every four hours lecture is equivalently divided into theoretical and experimental. The presented methods are immediately demonstrated in the laboratory in groups of maximally three students organized as research teams. Each team ha a tutor at hand to guide the students through the experimental task and to solve an eventual problems. One student is designated a team leader and is responsible for the proper fulfilment of the experimental task and prepares a experimental report at home and hands it back in one month time.

Syllabus of lectures:


1.Experimental mechanics and stress analysis. a) Measurement and transducers of displacement, strain, distortion, force, torque, pressure. b) Resistance strain gauges, photoelasticity, brittle coatings, holointerferometry, moiré techniques, thermoelasticity, digital image correlation.

2. Experimental dynamics. a) Basic vibration theory, shakers, transducers for acceleration, velocity and dynamic displacement measurement, stroboscope. b) A/D conversion, digital data recording and processing , statistical and FFT vibration analysis, damping, balancing, multi-parametric vibrodiagnostics.

Keywords: Mechanical and dynamical sensors, Experimental Stress Analysis, Experimental Dynamics, digital image correlation.
