Abstract

Since the beginning of the Turbo machinery, modal analysis has been crucial to the designers and operators. Low-cycle fatigue (LCF), high-cycle fatigue (HCF), environmental attack, creep, oxidation, erosion, and embrittlement are the usual causes of blade failure. The eigen value extraction for the flexural and torsional modes is obtained by modeling and analyzing the turbine blade using the finite element approach in this work. A circular crack along the blade’s leading edge is used to imitate damage from foreign objects. The increase in the structure’s bending stiffness was discovered to be caused by the stretching brought on by the centrifugal inertia force as a result of the blades’ rotation. This led to the highest operational Von-mises stresses; the goal is to give designers knowledge and insight to extend the lifespan and efficiency of gas turbines.
