Abstract
Nowadays, the implementation of an accurate non-destructive technique for the measurement of mechanical properties in small samples has become a main subject of interest due to the recent development of MEMS and intelligent materials, which need a safe procedure for their characterization.In this work we study a non-destructive method for determining the Young's modulus of an aluminium circular plate. Our technique is based on Electronic Speckle Pattern Interferometry (ESPI), a mechanical loading setup, and digital processing, which allows to obtain accurate values of Young's modulus for the sample agreeing those values from the literature.
