Testing of workpiece TG.19-PI.51

Rad se bavi problematikom udarnog rada loma. Detaljno se opisuje metoda ispitivanja udarnog rada loma po Charpy-u. Metoda ispitivanja po Charpy-evom batu jest standardizirana metoda pomoću koje se određuje količina apsorbirane energije koju materijal apsorbira prilikom loma. Ispitivanjem udarnog rada loma nastoji se utvrditi kako će se ponašati ispitni materijal u uvjetima udarnog opterećenja. Odnosno, nastoji se utvrditi da li ispitni materijal ima žilava ili krhka svojstva pri nekom zadanom opterećenju, te hoće li imati krhki ili žilavi lom pri zadanim uvjetima ispitivanja.The thesis main subject is impact testing. Charpy pendulum impact test is described in detail. It is a standardized method that is used to determine the amount of energy absorbed in the material during fracture. Using this test method the focus is to determine how a test material is going to behave during an fracture impact. The result will show if the material has brittle or ductile characteristics at a given load and it will show if the test material has a brittle or ductile break under the given test conditions
