Abstract


In this work, we have used the speckle interferometry technique and 3-steps-phase shifting to evaluate the displacement fields induced on a sample by mechanical load. The specimen was a brass sheet metal, 3 mm thick and an area of 210 mm$\times$3 mm. The sample was tested on an Instron machine working in tension at a constant speed. The mechanical load was controlled by using of a computer. Additional to the displacement fields, stress fields and Young's modulus were obtained.

Keywords


Optical metrology; speckle interferometry; mechanical stress fields; Young's modulus
