Abstract

Statičko vlačno ispitivanje jedno je od osnovnih ispitivanja kojim se utvrđuju mehanička svojstva materijala. Ponašanje materijala pri razvlačenju ovisi o njegovoj mikrostrukturi koja je funkcija kemijskog sastava i tehnoloških parametara obrade. Međutim, dodatan je utjecaj i nekih vanjskih čimbenika: temperature ispitivanja, geometrije epruvete, brzine prirasta deformacije ili opterećenja, ali također i frekvencije uzorkovanja podataka tijekom ispitivanja na računalom upravljanoj kidalici. U ovom radu obrađeni su rezultati statičkog vlačnog ispitivanja čeličnih uzoraka različitog kemijskog sastava ispitanih uz različite frekvencije uzorkovanja podataka, te doneseni odgovarajući zaključci.

Abstract (english)

Static tensile testing is one of the basic tests used to determine the mechanical properties of materials. The behavior of the material during stretching depends on its microstructure, which is a function of the chemical composition and technological processing parameters. However, there is an added influence of some external factors: temperature, geometry of the test sample, rate of increase of deformation or load, but also the frequency of data sampling during testing on a computer-controlled test machine. In this paper the tensile test results were processed for steel samples of a different chemical composition tested with different data sampling frequencies, and an appropriate conclusion was reached.
