Abstract:How to accurately predict the springback in ship hull plate air-bending forming process is a key factor. The finite element numerical simulation technology has provided a favorable tools for solving the problem of spring- back. Based on the problem of building mathematical model of numerical simulation for springback of ship hull plate in air-bending muhi-point technique, the paper focuses on the introduction of constitutive model, element type, numerical calculation method choice and the contact and friction processing, which lay the foundation for re- search of springback simulation.
Keywords:ship hull plate  springback  numerical simulation
