Analysis of load capacity of selected welded structural joints under static and cyclic load
Peč, Michal ; Vlk, Miloš (referee) ; Vosynek, Petr (advisor)
Welding is a widely used method of connecting components because of its efficiency, great value and almost endless possibilities of join types. A great variability of geometrical configurations of welds is problematic due to the assessment of the weld joint. Depending on this topic this thesis was focused on the assessment of weld joints statically and cyclically. Work in the first part deals with the search of methods for evaluation of welds and depending on identified options is subsequently selected American standard AISC assessment of welded joints. The method is applied into FEA analysis and simple welded joints are evaluated. Using FEM are computed three examples on which a comparative analysis was performed. Comparisons were made with the analytical solution based on changes in the parameters of the computational model. The change is primarily related to material properties, mesh size and division of the weld on segments. On the basis of knowledge from analysis of simple joints, method was extended to more general welded joints with the possibility of determining the maximum loading force.

Design of Welded Joints
Kojecký, René ; Doman, Jozef (referee) ; Dlugoš, Jozef (advisor)
This bachelor thesis deals with international and standardized approaches of weld assessment. The aim was to create a clear set of rules and differences of individual methods. The processing was based on the available literature. The first part is devoted to a research study that deals with this issue. Subsequently, three methods were selected for processing and evaluation using FEM.
