The viticulture Lahofer
Čech, Richard ; ing.arch. Lukáš Ležatka, Ph.D (referee) ; Pavlovský, Tomáš (advisor) ; Kacálek, Petr (advisor)
This bachelor thesis extends the bachelor’s studio project aimed at creating a survey on a new building for Vinařství Lanhofer company. The considered area lies in the territory of Dobšice near Znojmo and with its slightly rolling landscape is used for agricultural purposes. The mentioned trapezoid building site faces southwest, at the time was covered with vineyard and was bordered by minor roads connecting the plot to Dobšice and Suchohrdly. Building a new production site that would be able to produce up to 60 thousand bottles of wine, could be also used as storage space or would incorporate related services was intended. There were premises for public use, formal events or wine-tasting planned. The layout included restaurant with outside seating, sanitary facilities both for visitors and employees. Such a large-scale production of wine could be almost considered an industrial production that set up the main idea of the design. The basic clue of this project is searching an ideal shape of the production area that – in historical context of industrial buildings – is saw-shaped rooftop silhouette. The material concept of the building is based on visual and logical separating of production premises from public spaces that had been achieved by distinguishing both areas by using different facade cover. Stainless steel representing production environment and Cor-Ten patina steel panelling describing eternal wine maturation.

Analysis of stress field in the vicinity of fatigue crack in IPE made from stainless steel
Juhászová, Tereza ; Malíková, Lucie (referee) ; Seitl, Stanislav (advisor)
The master thesis is focused on analysis of stress field in the vicinity of stress concentration of stainless steel IPE beam loaded in tree point bending. Theoretical part includes introduction to fracture mechanics with basic terms, principles and variables used to describe fatigue behaviour of material. It concludes teoretical grounds of fracture tests which are future focus of the thesis, methodes used by numerical softwares and methodes used to obtain numerical results. Practical part includes comparision between two and three dimensional numerical models in three point bending, IPE model with different crack front shapes and plastic zone size. Numerical modelling was processed in Ansys Mechanical APDL. Thesis also involves results of experimental testing evaluated using numerical model.

Production of drinker
Vašíček, Jan ; Dvořák, Milan (referee) ; Císařová, Michaela (advisor)
The diploma thesis of the master's study in the field of M2I-K presents a design of a hollow rotating part made of metal sheet with a tapering bottom. Deep drawing technology was chosen as the best suited option for production without thinning the wall. Stainless steel was chosen as a source material for production parts in compliance to ČSN 172 40. The drinker is produced by three drawing operations where each operation is performed separately on a standalone press CTH 250 developed by ŽĎAS a. s. A sheet measuring 1500 x 3000 x 1 mm with diameter 428 mm was evaluated as the most economically viable for production of a semi-finished product – rondel. For one year production produced in a series of annual volume 100,000 pieces.

Optimizing the production process chamber 80C
List, Jaroslav ; Zemčík, Oskar (referee) ; Dvořák, Jaromír (advisor)
The aim of this bachelor thesis is to suggest optimisations of the production process of chamber 80C at various stages of production and assess their applicability. The main emphasis is on reducing production costs. In the first chapter we analyze specifications and requirments of the customer. There is a suggested optimisation of procedures. In the theoretical part of thesis we analyze materiál, welding methods and production technologies used to manufacture parts of the working chamber. In the practical part we assess the applicability of possible methods of welding and cutting. We will choose parts of the weldment suitable for optimization and dedicate the optimisation suggested in the first chapter. In the conclusion we assess the optimisation suggestions from the economic point of view.

Expected Fatigue Crack Propagation with Selected Geometric Shapes in IPE 80
Juhászová, Tereza ; Seitl, Stanislav ; Miarka, Petr
The focus of this contribution is to investigate fatigue behaviour of I cross-section beam. Stainless steel IPE beam with initiate concentrator is loaded in three point bending and the crack growth rate is analysed for various crack front shapes. Stress intensity factor size in the crack tip is being investigated in relation to growth rate of discontinuity. Load number of cycles is predictable basing on hypothesis of fatigue behaviour of material and the results are compared to experimental results of studies performed on compact tension specimen made from the similar material.
