Possibilities of the Tensile Test
Nevřivý, David ; Harant, Martin (referee) ; Řiháček, Jan (advisor)
The Bachelor’s thesis deals with the possibilities of tensile testing, the parameters of the test specimens, testing machines and the equipment which can be used in this test. Based on the literature review, the thesis explains the test principle, the measurement process and the strain and stress characteristics detected by the test. The thesis then focuses on the test specimens, their geometry, the method of their sampling and gripping into the machine. When describing the machines and equipment used in tensile testing, the thesis explains the functionality of these and their different types. The work also covers special types of tensile tests, namely those using elevated temperature, high-speed deformation, and cyclic or multiaxial stress. The final part of the thesis examines the current trend of evaluating the tensile test using 3D optical measurement systems

Destruktivní metody testování materiálu
Veverka, Vilém
The submitted bachelor's thesis deals with destructive methods of material testing with a focus on tensile testing and material fatigue. The aim of the bachelor's thesis was to prepare an overview of individual destructive methods of material testing and comparison of tensile diagrams of samples. In the bachelor's thesis, 3 types of samples were investigated, which were printed on a Prusa i3 MK3s 3D printer from ABS, PLA and PETG materials. Test specimens were modeled in Fusion 360 according to ASTM D638. The tensile test was performed on a ZDM 5/51 universal tensile machine according to the ASTM D638 standard. The results show that the sample made of PLA material has the highest tensile strength of 41,23 MPa.
