Interkonverzija materialnih funkcij: Ali je potrebno za določitev časovnih in dinamičnih materialnih funkcij eksperimentalno izmeriti obe funkciji?

Možina, Matevž (author), Slemenik Perše, Lidija (mentor)

Določevanje časovnih in dinamičnih materialnih funkcij je časovno potraten postopek. Z uporabo interkonverzije lahko izmerimo le eno izmed funkcij, medtem ko drugo izračunamo. Metodo interkonverzije smo preizkusili na PA6. Po pripravi vzorcev za testiranje smo določili temperaturo steklastega prehoda in območje linearnega viskoelastičnega odziva materiala. Sledile do meritve časovnih in dinamičnih materialnih funkcij. Na podatkih obeh funkcij smo izvedli metodo interkonverzije. Rezultate interkonverzije smo vrednotili in določili smiselnost uporabe interkonverzije za določevanje materialnih lastnosti.

• Title: Interconversion of material functions: Is it necessary to experimentally measure time and dynamic material functions to determine both?

Abstract

Determining time and dynamic material functions is a time-consuming process. By using interconversion, only one of the functions can be measured, while the other is calculated. The interconversion method was tested on PA6. Firstly, samples were prepared for testing and glass transition temperature, as well as the range of linear viscoelastic response, were determined. Secondly, time and dynamic material functions were measured. The interconversion method was used with data obtained for both functions. The results of interconversion were evaluated and the feasibility of using interconversion for determining material properties was established.
