Interface Performance of Electrodeposited Nickel Coating in Stamping Process

Finite element method was used to simulate the stamping process for electrodeposited nickel coating by using a plane model.The stress and strain fields at the interface were obtained within the nickel coating and steel substrate.The computational results shows that the value and property for the stress at the interface were variational.Generally,the normal stress was between -50~50MPa,and the shear stress is between -40~30MPa.The strain in the nickel coating might be much greater than in the substrate.But they were approximately matchable during the stamping process.
