Simulation of microstructure defects Creep on nickel-based superalloys by Genetic Algorithm
Rased on finite element method and genetic algorithms dynamic mathematical model is established, and the simulation of stress distribution around the defects of single crystal nickel-based superalloysis also established with ANSYS. After the change of stress field with time is analyzed, the result is compared with that achieved through numerical calculation and experimental analysis. The comparison shows that the combination of Finite element method and genetic algorithm is an effective way to micro-simulation, a model is established and simulated for nickel-based superalloys by finite element Method tool, the paper also analysis the stress field of microstructure defects. An Optimization Method is used to the Simulation by Genetic Algorithm, and the results are compared with experimental analysis. The comparison shows the model and Algorithm are correct and can provide basis for the study of creep features and microstructure evolution
