FINITE ELEMENT ANALYSES OF TURBINE DISC WITH SURFACE CRACKS

Bhanu Murthy Soppari

Abstract: In Aircrafts, Gas turbine discs are critical engine components, which must endure substantial mechanical and thermal loading, such air facts will be in trouble if an induced cracks develop and may gradually affect the whole engine function and leads to failure. In order to overcome the problem turbine life span has to be predicted using the approximate methods of evaluation (Ansys workbench software). There are a number of investigations devoted to both failure analyses and life assessment of turbine discs. Therefore, it is important to get approximate life of the turbine disc by simulating the fatigue damage of crack growth rate, and are essential in determining either the likely failure modes or the component replacement intervals to prevent failures under normal operating conditions.
