Abstract

Split Hopkinson Pressure Bar test omogoča določanje mehanskih lastnosti materialov pri hitrostih specifične deformacije od 10^2 do 8 x 10^3 s-1. Pri tako visokih hitrostih specifičnih deformacij, kovine lahko prenesejo višje obremenitve, kot pri statičnem obremenjevanju, ki pa jih vzdržijo zgolj kratek čas. Namen diplomskega dela je konstruiranje in izdelava kompletne tehnične dokumentacije, sestava ter umerjanje novega Split Hopkinson Pressure Bar preizkuševališča na Fakulteti za strojništvo Univerze v Mariboru. Geometrija in sestavni elementi preizkuševališča so bili določeni na podlagi izkustvenih priporočil v literaturi. Vrednotenje rezultatov umerjanja udarnega telesa je temeljilo na primerjavi s teoretično izračunanimi podatki.

Secondary title:	Design, assembly and calibration of SHPB test apparatus
Secondary abstract:	Split Hopkinson Pressure Bar test allows us to determine mechanical characteristic of materials, at strain rates ranging from 10^2to 8 x 10^3 s-1. Metalic material can whitstand much higher loads at such high strain rates, but they can whitstand it for a shorter period of time. The purpose of this bachelor thesis is to design, build and calibrate a test aparatus for such testing, called Split Hopkinson Pressure Bar test aparatus at the Faculty of mechanical engineering at the University of Maribor. Part geometry of the test aparatus has been assigned with respects to currently known practical guidelines in the literature. Resoult analysis of the calibration of the impactor body is based on comparison with theoretical computed data.
