Abstract
The introduction of new materials in Mechanical Engineering is one of the main tasks of scientists and engineers. At present new technologies that allow the study, characterization and measurement of important mechanical states in new materials are being developed continuously. These techniques include the Optical Techniques of Measurement that use laser as an important tool in the information processing and interpretation. These techniques also involve the Electronic Speckle Pattern Interferometry (ESPI). The present investigation shows the development and implementation of ESPI technique in the study and characterization of composite tube junction. The technical characteristics related to this technique implementation are included in this paper. The strain field caused by different applied actions is also presented. The advantages and disadvantages of the use of this technique are shown and they are compared to other traditional and optical measurement techniques.
