Strain, stress and strength analysis of the frame construction.
Kysilko, Vít ; Damborský, Petr (referee) ; Vrbka, Jan (advisor)
The bachelor´s thesis is intent on the computation of a plane frame which is used for test the resistance of composite tubes to a changing pressure. As a computational model I used simplified frame loaded by solitary forces which work eccentrically from the axis of symmetry of the frame. Because I cannot exactly use the theory of simple elasticity and strength in this task I make two calculations with various shapes of midline. This is twice internally statically indeterminate task, appropriate deformation conditions were solved by Castigliano’s theorem. Bending stress is dominant but in calculation is also composed energy of normal and displacement forces. Inspection of cyclic fatigue was made in possible hazardous places. Analytic calculation was carried out in MAPLE 12 and it was compared with Finite Element Method analysis with Ansys Workbech 12 software.

Strength design of the press frame construction and the compliance calculation at the load position.
Dobeš, Martin ; Suchánek, Miroslav (referee) ; Vrbka, Jan (advisor)
The bachelor's thesis is intent on the calculation of a plane frame which is used for hydraulic press. The theoretical basis for the calculation is mentioned in the first part of this thesis. The calculation of a concrete exercise according to the task set in the bachelor's thesis is in the second part. As a frame model we used a plane frame with two crossbeams. The load on the plane frame is interpreted by solitary forces which work upon the crossbeams. The calculation uses the Castiglian's theorem to specify the unknown parameters from deformation conditions. The calculation considers flexion energy of tensity. In the next part of the calculation, we consider the energy of tensity caused by vertical and normal shear for comparison. Coordinates of the load position can be changed at will. The final results of the thesis are a concrete frame proposal and an examination of pliability of the frame. The calculation was carried out in MAPLE 11 software.

Design and static analysis of the sports hall roof
Chudějová, Ludmila ; Zídek, Rostislav (referee) ; Vlk, Zbyněk (advisor)
This bachelor thesis deals with design and static analysis of sports hall roof. The program Dlubal RFEM 5.11 were created models of plane frames and calculated using the finite element method. These models were compared with each other. The values of internal forces were taken from RFEM program. Subsequently, one of the load cases was verified by manual calculation.

Strain, stress and strength analysis of the frame construction.
Hrubý, Jaroslav ; Vlk, Miloš (referee) ; Vrbka, Jan (advisor)
This work deals with the stress and strain calculation as well as with the safety evaluation at the plane (2-D) frame loaded by the individual force F. The aim of this work is not acquiring the use of cutting-edge computer programs to determine the stress and deformation, but to learn how to use practically the basic calculation methods being taught at the subject Strength of materials to get practical experience with the application of these calculation methods.
