Computational tool for a stress-strain analysis of the mechanically loaded circular and annular plate
Dohnal, Jakub ; Majer, Zdeněk (referee) ; Ševeček, Oldřich (advisor)
The bachelor's thesis primarily deals with the creation of a computational tool for stress-strain analysis of rotationally symmetric circular and intercircular plates. The commercial software MATLAB and its component APP DESIGNER were used for this purpose. The program uses analytical relationships of general solid mechanics to solve differential equations for several types of plates and loads. Part of the bachelor thesis is also a parametric study comparing the outputs of analytical and numerical model based on the finite element method, aimed at identifying the practical application of the analytical solution and its accuracy for a particular case of the plate.

Cast-in-place tank of sewage plant
Čožík, Martin ; Šiška, Radek (referee) ; Strnad, Jiří (advisor)
The thesis deals with the design and assessment of monolithic reinforced concrete structures tanks and wastewater treatment plants in accordance with applicable standards and drafting drawings. The tank is divided into individual solved parts: base plate, walls and ceiling plate. These parts are designed according to the ultimate limit states and serviceability. Resolves an assessment of the foundation structure according to the second geotechnical categories.

Strain-Stress analysis of pig femur
Legerský, Radek ; Valášek, Jiří (referee) ; Florian, Zdeněk (advisor)
This master’s thesis deals with the strain-stress analyses of the pig femoral bone in physiological and pathological condition. Pathological condition is determined by a significant defect in diaphysis of the bone fixed by using direct angular stable locking plate with screws. The thesis describes the creation of computational models with special focus on bone tissues models of material, which are based on analysis of digital images from computed tomography (CT). There are created and analyzed three types of computational models: the first one corresponds to physiological condition of femur, the second one to femur with significant defect and fixation plate and the third one to femur with significant defect, fixation plate and rod. Every model is loaded in three ways: the first of them simulating the experimental conditions of pressure testing of the femur, the second one bone stress in the sagittal plane and the third one stress by using load determined from probational release of the pig hind limb. Strain-stress states are determined by finite element method using Ansys computational system. Gained results of stress and strain are compared with experimental measurements. The thesis presents a basic idea of the mechanical behavior of porcine femur and porcine femur with significant bone defect.

Sugar storage tank
Kotík, Libor ; Musil, Jiří (referee) ; Zich, Miloš (advisor)
The matter of this thesis is static design and examination of prestressed storage tank to 50000 tons of sugar. Computational model of the steel roof structure is processed and its effect on the silos. Loads is provided of sugar. Optimal design is performed and assessment ultimate and serviceability limit state reinforced concrete and prestressing horizontal silo wall including local load. Next, it is performed the design of a reinforced concrete of the plane bed and column and assessment at the ultimate limit state. The thesis is also drawing documentation, technical report and visualization of construction process. The aim of this work is to the design of the main components based on the required storage capacity tank, mechanical properties of the stored material and technical amenities.

Analysis of process for production of small plates
Talanda, Jiří ; Fiala, Alois (referee) ; Koška, Petr (advisor)
Theme of the Master’s thesis is analysis of process for production of small plates. Main parts of the thesis are analysis of the production process, process mapping, data capture, analysis of the data by Pareto analysis and find causes of nonconformities. Causes analysis is based on data analysis and process observation. It is divided to chapters by factors which are influencing the process. Optimization measures are designed with regard to their simplicity of realization and system in organization.

Production System Simulation and Analysis
Hromková, Ivana ; Křivka, Zbyněk (referee) ; Zendulka, Jaroslav (advisor)
The work deals with creating of simulation model of production system (foundry) and its analyze. Simulation of production systems is discussed in the introduction as well as basic principles and processes during simulation model making. Next chapter describes problems arise when such type of systems are solved. Next issue about virtual fabric is discussed. Information regarding virtual fabric has been obtained from Siemens conference. Follows views of simulation tools specialized on manufacturing systems. In last one chapter is taking up of implementation of simulation system. The whole process of creating of simulation model which consists of making conceptual model, abstract model, description of model making, analysis outcomes and experimentation with simulation model.

Cranked ceiling slab
Maršalová, Jiřina ; Koláček, Jan (referee) ; Strnad, Jiří (advisor)
This bachelor work deals with the suggestion of spatially cranked concrete plate of family house and spiral staircase. The concrete desk of asymmetrical shape, which is reinforced in both directions, creates a ceiling construction of basement and is simply supported on the perimeter walls. The construction is dimensioned to the limiting state of carrying capacity and usability. Software programme RFEM 4.10 has been used for the calculation of internal forces.
