Application and finite element simulation of plastic blanking deformation
The study is focused on the way get overall rigidity equation, which is needed to establish the physical equation by using the Markov principle of Lagrange multipliers, and discrete and linearizing it. The simulation method can be easily realized through simulation software. This paper discusses the finite element simulation steps, and illustrates separate and the linearizing algorithm as well as the rigid equation solutions in numerical simulation. But it should be noted that when the finite element carries on simulating to a certain degree, the simulation will be broken off for serious distortion of discrete grid unit, which need the corresponding algorithm to transmit the former units data to the unit which is afresh separated, then automatically distinguished the boundary condition and contact the boundary. When solving rigidity equation, a fast method which can assure the requests of simulation and restraining the algorithm is still needed. This paper provides a foundational theory for the project application.
