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.

Methods of solving stress rods bar system
Lamrich, Martin ; Krpalek, David (referee) ; Florian, Zdeněk (advisor)
The bacalors thesis deals with methods of solving stress rod bar systems and their mutual comparasion. In the first part of this work is mentioned theoretical basic for the subsequent calculations. Graphical, analytical and numerical methods of solving stress rod bar systems are applied to representative examples. Each of the examples contains theoretical part where are mentioned advantages, disadvantages and suitability for use of the methods. Due to Finite Element Method in ANSYS software is carried out a numerical calculation on the solved rod bar systems. Conclusion is intent on summary of work and comparation of results. Analytical calculations were carried out in MATHCAD 14 software.
