Abstract
In modern development, there are various reqirements that include optimization from many aspects, while optimization itself often reqires unavoidible changes in geometry. This types of changes can significantly affect the distribution of stress in construction element and we call them the stress concentration. Due to the influence of localized maximum stress, the overall strenght of the construction element is reduced. Because of overall strenght reduction, there is a need for additional... More analyzes of local areas of construction element to determine safe side of calculations. While the check of critical sections of construction elements is mainly performed by numerical analysis, there are often cases where some of the input parameters important for reliable numerical analysis are unknown. For example, such parameters are considered to be: mechanical properties of material, boundary conditions, unknown external loads and other inputs required for conducting reliable numerical analysis, particulary in analysis of conceptual construction elements. In this case, experiments should be carried out. This thesis deals with the process of analyzing specimens with and without stress concentrators, loaded in pure bending, where the results obtained by analitical calculations, numerical and experimental analysis are critically commented. In addition, a detailed process of carrying out each of the above analysis and calculation is presented. The results where obtained using experimental method called digital image correlation, while results of numerical analysis where obtained using the finite element method. Also there have been given some of the possible solutions for getting qualitatively beter results. Less
