The article presents specialized software methods for reducing stress concentration. Objects of study are cylindrical test specimens subjected to axial loading. Notching with different shapes and sizes on the specimens were formed to reduce the stresses in the endangered areas. The geometric parameters of notches identified through the specialized built-in modules to the ANSYS software. An analysis performed were to show the influence of stresses acting on the fatigue limit during different cycles. The results of the study were present in a graphical form.

The article presents studies related to the reduction of stress concentration acting on prismatic specimen subject to axial loading. Using ANSYS software, a topological optimization was performed which aims to reduce the stresses in the endangered areas. The aim of identification of the geometric parameters accomplished after the completion of topological optimization of the objective function is to minimize the stresses in the engaged areas. An analysis performed were to show the influence of stresses acting on the fatigue limit during different cycles. The results of the study were present in a graphical form.
