Abstract:

The proposed constructions have to meet their use in terms of shape, dimensions and above all, strength. Parts of the structure are loaded by external forces. The load on the structure is examined in all parts and directions. Parts of the structure are stressed by a combination of basic types of stress. One of the basic types of stress is pull or pressure. The investigation of the part of the structure under tensile-compression stress is important because of the deformation, stability and strength of the structure as a whole. Analytical solution, classical experiment or modelling FEM can be used to predict the stress of structural parts. Currently, the most preferred solution is FEM numerical simulation. Numerical simulation has a more purposeful use in the solution of structural stability. The article contains the solution, tensile stresses for a steel rod, numerical simulation using the FEM method in the ANSYS program and analytically.
