Abstract

The presented paper is devoted to the whole complex of problems relating to the experiments of the mechanical fatigue for the determination of the materials parameters and characteristics of the structural properties. The experimental determination of Wöhler fatigue curve and knowledge in relation to the material data for the tested construction material is based on the experimental results of the testing machine SCHANCK used for determination of the mechanical fatigue. In the given work, there is the introduction of the research in the field of the fatigue based on cyclic loading by bending and moreover, the given research is combined with the modern computational methods of the mechanics of continuum. In relation to the numerical analysis, the given thesis is focused on the creation of the computational model according to the geometry of the tested sample in an experimental way and this computational model can help us to obtain the most reliable results for the simulation of the loading with utilisation of the computational program system on the basis of the finite element method. The total numerical time was also taken into account because of the achievement of the fast response to the change of the material, geometrical and other parameters during the creation of the computational model. The obtained results based on the experimental analysis as well as numerical analysis were mutually compared. The numerical analysis and experimental measurement can be also applied for the other types of materials.
