This work is primarily focused in utilising a technique to assess low cycle fatigue life of steam turbine blade. Two approaches are employed here, first is based on the linear elastic finite element analysis. Fictive elastic results are recalculated using Neuber's rule. Second approach is based on elastic-plastic Finite Element analysis (FEA). Strain amplitude approach is followed through Universal slope method and Coffin-Manson equation to determine the number of start-up and shut down cycles Proper blade design with conservative stress levels is important for reliability in rotor blade design. Finite Element Analysis based fatigue tools enable reliable fatigue life calculations to be done at the design stage of a development process and a proper design methodology is important to predict the catastrophic failure of turbine blade due to fatigue.

This article describes repetitive corrugation and straightening processes with Constrained Groove Pressing parameters such as Wt. % of Sic, strain rate, Number of passes, Thickness of the specimen and heat treatment process. Using Taghuchi robust design method to determine the optimal condition for Al6061/Sic metal matrix composites. The optimal conditions for tensile strength are Wt. % of Sic of 15%, strain rate of 1.5 mm/min, Number of passes of 7, specimen thickness of 4 mm and heat treatment of 3 hrs.Experimental results indicate that number of passes and Wt. % of Sic are most influencing parameters and other parameters are less significant effect.
