Solution of bendig technology problems of thinn walled profiles
Matoušek, Karel ; Forejt, Milan (referee) ; Samek, Radko (advisor)
Reconnaissance of problems and parameters of square hollow profile bend. Finding (identification) of deformation of cross-section. Finding of suitability of unannealed material for component part. Finding of mechanical characteristics of welds and influence of their bend position. This finding was done on the basis of comparison of tensile tests and consequently aplicated to specific part where the suitability for use of unannealed material were proved.

Design of universal wire bending machine
Nezval, Jan ; Svoboda, Pavel (referee) ; Brandejs, Jan (advisor)
This bachelor’s degree thesis deals with the specification, design and subsequent construction of a CNC wire bending machine for use with aluminium alloys. The machine is designed for bending suspension hooks and tension springs for use in anodizing processes. This thesis also briefly describes the anodizing process, outlines specifics of the suspension parts, the current state of the wire bending machine market and the solution design. Finally there is a breakdown of the individual parts.

Gravital conveyor for transport
Fatka, Milan ; Pokorný, Přemysl (referee) ; Kašpárek, Jaroslav (advisor)
The aim was to propose a conveying gravity path for the transport of steel casting in the context of inter-transfer service. The conveyor is dealt with valid norms with regard to simplicity of design, production and assembly (disassembly) with broad use of standardized parts. It was also seen to be done to take advantage of the proposal in solution of similar specification.

Static solution of monolithic reinforced concrete structure
Kunčík, Martin ; Švaříčková, Ivana (referee) ; Zlámal, Martin (advisor)
Bachelor´s thesis deals with statical solution of the office building structure. The subject of the solution is a reinforced concrete monolith- frame construction. It consists of a ceiling board, rungs, beams, columns and footings. Assessment of construction is carried out for all assessed elements considered for first limit state – carrying capacity and the rungs on the second limit state - usability.

Statical solution of reinforced concrete structure
Velecká, Renata ; Kostiha, Vojtěch (referee) ; Zlámal, Martin (advisor)
Bachelor's thesis deals with statical solution of structure of the office building. The theme of solution is reinforced concrete monolithic point-supported ceiling slab. It's supoported by columns and whole structure is completed by two reinforcing cores and reinforcing wall. Structure review is done according to the first limit state – carrying capacity.

The estimation of crack initiation for a bent sample with V-notch
Majer, Zdeněk ; Hutař, Pavel ; Náhlík, Luboš
The aim of this paper is to investigate the beginnings of crack propagation from sharp V-notches. Stress distribution around the tip of a V-notch is described on the basis of linear-elastic fracture mechanics. The V-notch is a singular stress concentrator with a singularity exponent dependent on the V-notch opening angle. The stability criteria are generalized for a stress singularity different from 0,5.
