METHOD FOR MEASURING THE ELASTICITY OF MATERIALS
Journal Title: International scientific journal Science and Innovation - Year 2023, Vol 2, Issue 9
Abstract
Currently, considerable attention is paid to improving the reliability of all categories of buildings and structures. Especially for the analysis of deformation and displacement field, the use of various methods is urgently required, one of which is digital holographic interferometry. For the practical application of this method, the authors have developed a technique for processing digital holographic interferograms. Digital holographic interferometers (DHI) used to measure the movements of diffuse-reflecting objects have two unique metrological properties: ultra-high sensitivity to movements (fractions of a nanometer) and the ability to perform measurements simultaneously over the entire surface of the object. Therefore, the main problem in assessing the accuracy of measurements is the lack of exemplary measuring instruments with higher or even similar characteristics. To assess the accuracy of the measurement information in the laboratory of holographic research, the results of the analytical calculation of the elastic line (deflections) of a beam of constant rectangular cross section were used as a comparison base when it was loaded with pure bending. The test results of the technique showed the convergence of experimental and calculated data.
