基于有限元的鼓泡试验模拟

Mechanical Model and Simulation of Electrodeposited Nickel Coating Steel Interface

采用ABAQUS内置的内聚力模型来表征电沉积镍涂层钢板的界面性能,运用张力-位移界面本构关系的界面力学模型,模拟了鼓泡试验的界面开裂过程,描述了界面从起始剥离到完全开裂过程的力学性能,得到了电沉积镍涂层钢板界面开裂的强度曲线,该方法以及所得的结果对板料成形的生产能起到一定的指导作用。

A built-in cohesive zone model of ABAQUS was used to present electrodepsited nickel coating steels interface performance,and studied the calculation interface model and damage criterion based on traction-separation law. The peeling and debonding process of interface structure were simulation which describes interface mechanical performance. The strength curves were gained for interface damages of the electrodeposited nickel coating steel.As is shown, the results are acceptable, so this method can be used as guidance for shell＇s forming manufactue.
