ABSTRACT

Gas turbines are essential for power generation and industrial applications, providing a reliable energy source. As global energy demands rise, improving turbine efficiency and power output becomes increasingly important. One of the critical components influencing turbine performance is the turbine blade, which operates under extreme thermal and mechanical conditions. Enhancing the durability and longevity of these blades is crucial to maintaining optimal turbine functionality over extended operational periods. This study focuses on selecting the most suitable materials for turbine blades and conducting fatigue analysis to ensure their reliability.

The research begins with an evaluation of five different materials based on their structural and fatigue properties. A detailed blade model is developed using CATIA software, providing an accurate representation for further analysis. ANSYS software is employed to conduct structural simulations, including stress and fatigue assessments. These analyses help identify materials capable of withstanding high temperatures and mechanical stresses while maintaining durability.The selection process prioritizes materials with the lowest stress levels and the highest fatigue resistance, ensuring improved performance and extended service life. By comparing fatigue cycles and stress distribution, the most optimal material for turbine blade applications is determined. This study contributes to the advancement of turbine blade design, enhancing the efficiency and longevity of gas turbines in power generation and industrial settings.
