Paper Abstract

It is described an Electronic Speckle Pattern Interferometer (ESPI) used for Young's modulus measuring of a new PVC material. The technique considers the construction of a small tensile testing machine that is good enough to apply loads on the polymeric specimens. A dual-illumination ESPI system is built up to measure specimen in-plane micro-displacements under the tension loads. For Young's modulus measuring, strain is required and determined by the force per area unit. Since the specimens have irregular traversal section, the self-imaging or Talbot-projected fringe technique is implemented for determining such a transversal section all along the specimen. Experimental results by using these optical techniques are shown, as well as, the measure of a new polymer Young's modulus.
