Determination of Selected Tensile Properties of the Sealed Joint on a Real Joint
Boháček, Adam ; Brandtner, Michal
This article discusses selected tensile properties of a sealed joint on a real joint. A real joint is a sealed joint that, when tested in laboratory conditions, comes closest to what the real application of sealant looks like in current construction practice. The Aquapanel cement board was selected as the base material for this test. Subsequently, two sealants were selected which, according to the manufacturer's recommendations, are suitable for sealing cement-based materials and were selected also as suitable primers for them. Tests of a real joint were made for these materials, which were subjected to a tensile test on a test device designed for this purpose. This was followed by an evaluation using measurements and visual inspection of the tested joints.

Modification of clamping part of the test machine RUMUL Cracktronic 160
Beran, Pavel ; Hutař, Pavel (referee) ; Mazal, Pavel (advisor)
This diploma thesis deals with the structural design of the chucking jaws for RUMUL Cracktronic 160 testing machine. This apparatus is used in the fatigue laboratory of Institute of Machine Design FME BUT. Simplification, speed improvement and better test sample griping are expected gains of the new clamping system. Solidworks system is used to create 3D model of the jaws. Stress analysis is created by Finite element method in ANSYS Workbench software.

Determination of the mechanical properties of materials used for 3D printing
Černý, Martin ; Sliwková, Petra (referee) ; Sedlák, Josef (advisor)
The thesis deals with the determination of mechanical properties of materials used for 3D printing (ABS, nylon and PLA). Standardized samples produced using a 3D printer using the Fused Deposition Modeling method were subsequently used for mechanical testing. The work is also extended to determine the mechanical properties of samples made by Soft Tooling. For the production of Soft Tooling samples, polyurethane resins SG 2000 and SG 145 were used. Individual materials were analyzed by mechanical tests (tensile test and hardness test). Surface integrity parameters have also been determined for 3D-printed materials. Parameters were selected from the individual tests (tensile strength, modulus of elasticity) ductility and hardness), which were subsequently statistically processed. The work is concluded by evaluating the results obtained, which were compared with the values given in material sheets.
