dc.description.abstractMerne trake su osnovni alat koji se koristi za merenje naprezanja materijala. U industriji se primenjuju već više od sedamdeset godina. Oblast primene mernih traka je veoma široka. Koriste se za merenja naprezanja mašinskih i građevinskih konstrukcija, pojedinačnih mašinskih delova, uređaja i pomagala u medicini itd. Merne trake se izrađuju od različitih materijala, u različitim oblicima i dimenzijama. I pored široke zastupljenosti, primana mernih traka može biti otežana u određenim vremenskim uslovima. Niska temperatura i povećana vlažnost vazduha veoma nepovoljno utiču na materijale pomoću kojih se merne trake postavljaju na površinu dela kaji se ispituje. Da bi se prevazišli navedeni problemi koriste se deformetri. U radu je ispitana mogućnost primene specijalno dizajniranog deformetra u obliku slova omega (Ω). Ispitivanja su izvedena u laboratorijskim uslovima, na prostoj gredi, pri dejstvu dinamičkih opterećenja. Glavni cilj ispitivanja bio je utvrđivanje stepena korelacije rezultata dobijenih direktnim očitavanjem sa mernih traka i rezultata očitanih sa deformetra. Analiza rezultata uporednih ispitivanja pokazala su visok stepen korelacije čime je potvrđena mogućnost primene 'Omega' deformetra na konstrukcijama koje su izložene dinamičkom opterećenju. .sr
dc.description.abstractStrain gauge is a basic tool used to measure the stress of the material. In industry, it has been in use for more than seventy years. The area of application of the strain gauges is very wide. They are used to measure the stress of mechanical and building constructions, individual machine parts, devices and aids in medicine, etc. Straing gauges are made of different materials, in different shapes and dimensions. In spite of the wide presence, the aplication of the straing gauges can be difficult in certain weather conditions. Low temperature and high humidity significantly negativly affect the materials used for placing the gagues on the surface of the part to be tested. In order to overcome these problems, deformeters are used. This study examines the possibility of using a specially designed deformeters in the form of a letter omega (Ω). Tests were carried out in laboratory conditions, on a freebeam, under the action of dynamic loads. The main objective of the test was to determine the degree of correlation between the results obtained by direct reading from the strain gauge and the results read by the deformeter. The analysis of the results of comparative tests showed a high degree of correlation, which confirmed the possibility of using 'Omega' deformeter on the structures that are exposed to dynamic load.en
