Numerical determining of the stress concentration factor around a shaft with a traverse hole

The main objective of this paper is numerical determining of the value of stress concentration factor around a shaft with a hole by the finite elements method, and the comparison of results regarding their accuracy. A shaft with a hole of certain dimensions with a ratio d/D has been analysed in this paper. Furthermore, general theory of stress concentration factors has been described, and basic equations have been given. After that, a general description of elements used in the analysis of a shaft with a hole follows, as well as the description of finite elements used in this investigation: Tetrahedral element – SOLID 92 and Hexagonal element - SOLID95. Solutions gained by the finite element method with the program package ANSYS 11 are shown and explained in details, as well as the mesh and applied boundary conditions for each single problem. Finally, we compared solutions gained with the above mentioned types of finite elements on the example of a shaft with a hole for certain ratios d/D and values known from the literature given by diagrams.
