Testing and Simulation Analysis on Fatigue Property of B1000 Steel

According to finite element fatigue analysis,the durability of vehicle and components was estimated.Meanwhile,the weakness of components can be understood and an improving method can be proposed based on the results from the finite element fatigue analysis.However,before the finite element fatigue analysis,the S-N curve of material should be obtained at first and the accuracy should be confirmed.The finite element fatigue analysis with B1000 steel plate widely used in the corporation is done and the simulation result is compared with data from fatigue test.The results show that the S-N curve is reliable and it can be used in the finite element fatigue analysis.
