Aplikace metody ESPI u vybraných inženýrských úloh

Abstract

Specified Thesis deals with Electronic speckle pattern interfeometry (ESPI), with subsequent accuracy verification of the method using Finite Element Method. In the introductory theoretic part describes the method of ESPI in connection with holographic method and used measuring instruments briefly are described. In the introduction, the following practical section describes the measurements on geometrically simple samples loaded in tension and bending. Performing the task's goal was to evaluate the accuracy and applicability of the method, based on field measurements of displacements, strains and stresses. The results of each measurement were compared with the analytical or numerical solution. In the next stage, the findings of the previous measurements were applied to the real parts, more precisely to the arm of testing machine and transverse beam of industrial washing machine.
