| Popis: | This paper presents the results of determining the fatigue crack growth parameters in aluminium alloy specimens 2024-T351 and 7075-T651, with different levels of previous corrosion, in the laboratory environment. Tests were performed, under the same load conditions, for each case of corrosion (without corrosion, 7 days of exposure in a corrosive environment and 30 days of exposure in a corrosive environment). All the tests were performed at room temperature. The analysis of the results includes changes in the basic parameters of fatigue crack growth, depending on the time of exposure to the action of controlled moisture. In addition, this paper gives a brief overview of modern design processes in the environment of computer mechanics and presents the results of the crack growth simulation, using the software package ANSYS. |
