| Abstract [eng] |
The stress state components of a welded pipe with a flat weld in dependence on the active load, on the geometrical parameters of the pipe and the weld (the internal diameter of the pipe, the thickness of the wall of the pipe and the height of the welded weld). On the mechanical characteristics of the materials of the pipe and the weld (the modulus of elasticity and Poisson’s ratio) were examined in the Master’s final project. Firstly, the analysis on the similar scientific literature was performed. After the investigation it was found that the most loaded zone is in the plane of a contact at the internal radius of the pipe. The more dangerous load is the internal pressure (its influence on the welded pipe is bigger than the influence of the axial load). The internal diameter of the pipe and the thickness of the wall of the pipe are the most influential geometrical parameters. It was found, that the modules of elasticity have bigger influent on the stress state than the Poisson’s ratios. |
