MARTINEZ, A.; RAYAS, J.A.  e  MADRID GARAY, J.C.. Medición de la evolución temporal de los campos dinámicos de desplazamiento mediante interferometría de moteado para una probeta de latón. Rev. mex. fis. [online]. 2010, vol.56, n.3, pp.262-267. ISSN 0035-001X.

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 × 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.

Palavras-chave : Optical metrology; speckle interferometry; mechanical stress fields; Young's modulus.
