FEA Fatigue Analysis on Turbine Blade


Perform Finite Element Analysis (FEA) of a bladed disk of an airborne gas turbine engine. This assembly consists of 50+ solid cast blades, a disk, and rivets. The operating temperature reaches approximately 800 °C for the blades and 500°C for the disk and rivets. The operating RPM is 37000.


By running an FEA structural stress analysis on the assembly, we aim to understand the behavior of the bladed disk assembly under these challenging operating conditions. The high temperatures and rapid rotation speeds subject the assembly to significant thermal and centrifugal loads. Understanding how these loads affect the assembly is crucial for ensuring safe and reliable operation of the engine.


In the stress analysis, we calculate the stresses and strains in the assembly under the specified loads. This analysis helps to visualize the stress distribution across the assembly and identify areas where stress concentrations occur. These stress hotspots could be potential areas of failure and need to be carefully monitored.

The fatigue life is another key factor that we need to determine. Given the cyclic nature of the operating conditions, the assembly is at risk of fatigue failure. By predicting the fatigue life of the assembly, we can estimate the duration for which the assembly can operate safely under the given conditions.


This FEA analysis can provide critical insights into the structural integrity and durability of the bladed disk assembly. The results can be used to refine the design, enhance material selection, and optimize maintenance schedules, ensuring the gas turbine engine’s long-term safe and reliable operation.
