Medición de la evolución temporal de los campos dinámicos de desplazamiento mediante interferometría de moteado para una probeta de latón

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.
