Abstract (Croatian)

U završnom radu je opisan fizikalni princip elastičnosti materijala, odnosno modul elastičnosti te metode njegovog određivanja. Modul elastičnosti je određen pomoću dvije metode. U svrhu provođenja ispitivanja pripremljeno je 3 vrste uzorka: aluminij, mjed i meki čelik. Ispitivanje je provedeno pomoću kontakntnog ekstenzometra, mehaničkog ekstenzometra i instrumentiranom metodom indentacije. Nakon provedenih ispitivanja provedena je analiza i usporedba rezultata, odnosno utjecaj raspona mjerenja i izabranih parametara ispitivanja te usporedba različitih metoda za određivanje modula elastičnosti.

Abstract

This work describes the physical principle of the materials' elasticity, i.e. Young's modulus of elasticity and its methods of determination. The elastic modulus was determined by two methods. In order to conduct the experiments 3 types of samples were prepared: aluminum, brass and soft steel. The test was performed using a contact extensometer, a mechanical extensometer, and an instrumentized indentation method. After the tests were performed, analysis and comparison of the results, i.e. the influence of the measuring range and selected test parameters and comparison of different methods for determination of the Young's modulus were carried out.
