20.500.12556/DKUM-20460 TESTIRANJE MEHANSKIH LASTNOSTI MATERIALOV - UPORABA UNIVERZALNEGA HIDRAVLIČNEGA APARATA TESTING THE MECHANICAL PROPERTIES OF MATERIALS - THE USE OF UNIVERSAL HYDRAULIC TESTING MACHINE Testirali smo mehanske lastnosti materialov, ki smo jih prvič preizkusili z novim univerzalnim hidravličnim aparatom. Uporabljali smo štiri različne materiale: aluminij, baker, medenino in jeklo. Aparat omogoča pet preizkusov: natezni, tlačni, strižni preizkus, preizkus trdote po Brinellu in globoki vlek po Erichsenu. Vsi preizkusi so v skladu z veljavnimi DIN oz. EN standardi. Pri testiranju materialov smo ugotovili, da na lastnost materiala vplivajo sestava, način obdelave in struktura materiala, zato lahko dobimo pri enaki sestavi vendar različnem načinu obdelave različne rezultate. Ugotovili smo, da je aparat primeren za učno pomoč pri predmetu Uvod v testiranje materialov v srednjih tehniških, gradbenih šolah in univerzah. Primeren pa je tudi za uvodne študije v industriji. We tested the mechanical properties of materials, for the first time using the new universal hydraulic apparatus. We used four different materials: aluminium, copper, brass and steel. The apparatus enables us performing five experiments: tensile test, compression test, shear test, Brinell hardness test and Erichsen deep draw test. All of the tests performed are in compliance with current DIN or EN standards. When testing the materials we have confirmed the conclusion that materials' properties are influenced by their composition, treatment method and their structure, so we can get different results when testing the material with the same composition but differently treated. We also concluded that the apparatus could served as an appropriate learning aid for the Introduction to testing materials class in high schools of civil engineering and universities. It is also appropriate for initial studies in industry. materiali mehanske lastnosti testiranje materials mechanical properties testing true true false [A.
