Analyzing valve component subjected to internal pressure for fatigue cyclic loading.
The finite element analysis to estimate fatigue lifecycle of the valve component was performed. The results based on the S-N curve showed that the valve component design was found to be safe for 14000 pressure loading cycles.
The valve component was analyzed using finite element method to determine the structural strength against the internal pressure loading. In order to assess the fatigue lifecycle, the data from the S-N curve for the component material was utilized. The results showed that the mean stress value during 14000 pressure loading cycles was well within the acceptable range. Hence, the valve component design was predicted to behave safe during the expected lifecycle without premature failure.
