Abstract: [cze] [eng]
Příspěvek prezentuje kombinovanou optickou metodu pro měření posunutí její aplikací na vyšetření deformací v okolí čela trhliny. Optická metoda spojuje metodu Kódovaného fotometrického sterea a Metodu interpolačních elips. Combined optical method for measurement of three displacement fields on flat specimens is described and applied for the evaluation of surface deformation of flat aluminum alloy specimen with central crack in tensile tests. The method utilizes two optical methods – Coded Photometry Stereo and the method of Interpolated Ellipses allowing the measurement to be performed simultaneously making it favourable for dynamical tests.
Keywords: aluminium alloy; crack tip displacements; optical measurement
