Analiza deformacji powierzchni próbek geosiatek z wykorzystaniem metody cyfrowej korelacji obrazu
Języki publikacji
Abstrakty
This article presents the results of tests on geogrids conducted using the Digital Image Correlation (DIC) method and those of numerical simulations of laboratory tests on the geogrid using the wide-width strip method. DIC allowed for the non-contact determination of displacements and strains for the entire surface of the samples of geosynthetics tested. The results of the laboratory tests and numerical simulations have been compared. The results of the tests and analyses indicate that the DIC method is an effective tool for evaluating the parameters of geogrids used in GRS systems and in pavement structures. In addition to the standard deformation image for the averaged base, analysis of deformations in any direction and at any point on the surface of the geogrid is possible. The measurement method applied also opens possibilities for validation of numerical models of geogrids made using the finite element method (FEM).
W artykule zaprezentowano wyniki laboratoryjnych badań geosyntetyków przeprowadzonych z wykorzystaniem metody cyfrowej korelacji obrazu (Digital Image Correlation) oraz ich porównanie z wynikami uzyskanymi tradycyjną tensometryczną metodą pomiarową. Badaniom wytrzymałościowym metodą szerokich próbek poddano geosiatki poliestrowe i szklane. W artykule zaprezentowano również numeryczny model przeprowadzonego badania. Wyniki symulacji numerycznych odniesiono do wyników badań laboratoryjnych. Zrealizowane badania materiałów geosyntetycznych oraz analizy uzyskanych wyników pozwoliły na sformułowanie szeregu wniosków. Pierwszym spostrzeżeniem było, iż dwuwymiarowa analiza deformacji metodą DIC pozwala na bezkontaktowe określenie całościowego charakteru pracy powierzchni badanego geosyntetyku. Daje to możliwość określenia rejonów najbardziej wytężonych, również poza obszarem bazy. Kolejną ważną zaletą metody jest możliwość analizy zagadnienia wartości i wektorów własnych wraz z wyznaczeniem pól przemieszczeń i odkształceń dla całej powierzchni badanej próbki. Rozwiązanie to nie jest możliwe przy wykorzystaniu tradycyjnej tensometrycznej metody pomiarowej. Istotne jest również otwarcie możliwość walidacji modeli numerycznych wykonanych przy użyciu metody elementów skończonych.
