At present magnesium alloy is the lightest metallic materials of practical engineering application, Because it has many special advantages, such as low density,high specific,excellent thermal conductivity,anti-electromagnetic interference,can be 100% recycled etc. This year, with the rapid development of electronic products, the amount of magnesium alloy is also substantially increased, which in this thin-walled magnesium alloy case is particularly great demand and it can only be resolved through plastic forming methods.Therefore, the study for plastic forming of magnesium alloy has become a hot whether in theory or in the business sector. Now ,with the rapid development of computer technology, simulation technique has been become more and more role in plastic forming of magnesium alloy research. However, the numerical simulation requirements the users has relatively high theoretical foundation. This limits its widely used in the domestic small and medium-sized enterprise. In order to expand the numerical simulation technology application in small and medium-sized enterprise. This paper develop a module for magnesium alloy numerical simulation which based on ABAQUS software. The main research contents in this paper can be listed as the following:Fully grasp and analysis of plastic forming of magnesium alloy based on the1) Based on the fully grasp and analysis of plastic forming of magnesium ,developing modules which suit deep drawing for sheet metal parts (circular and spherical). In order to increase the software-friendly, graphical user interface has been used in the development. In order to reduce the user input values of the material plastic deformation , The preserve and import of material plastic deformation value's menus have been developed in this paper.Meanwhile, the advantages and disadvantages of two different ways for development graphical user interface have been discussed.2) In order to broaden the application scope of ABAQU,the menus for determining whether the sheet metal forming process is quasi-staic or not and determining when fracture during sheet metal forming have been developed in the ABAQUS post-processing module. Finally, given some issues that should to noticed in the ABAQUS second development.3) Numerical simulation for ME20M has been processed which basis on the developed modules, and then through compared the results of simulation and experiment, we can verified the development modules are feasible.At last, based on the secondary-development modules, the keys factors which impact of magnesium alloy deep drawing have been simulated. Through these simulation ,hope it can provide the feasible guidance for the actual production.
