Verification
In the pre-analysis the maximum stress was calculated and to verify that our simulation was accurate a comparison must be made. In order to calculate the maximum stress of the simulation click on Add next to Results, and select Calculated Value. In the function drop down menu select Maximum and under the Variable drop down menu select Equivalent Stress then Evaluate. Very quickly the maximum stress of the stepped shaft is calculated and displayed.
The table below compares the calculated and simulated values for maximum stress in the stepped shaft. There is a negligible difference between the finite element calculation and the simulation result.
Calculated Value | Simulated Value | Percent Difference |
1376 psi | 1375 psi | 0.073% |
