In order to eliminate the lasting calculation bottleneck on application of finite element,we proposed a new method to accelerate the computation of FEM by using the existing modern GPU and programmable shading tool. In accordance with the features of GPU,we devised a method representing unit information and initial conditions,which converted all the unit calculations into rendering process.In this way,the simulation work of all the unit calculation of the internal force will be solved,and the shortcomings of lowly parallel level appeared ever before when it run in a single computer can be overcome.Studies show that this mean can improve efficiency and shorten calculating hours greatly.Aimed at the elasticity problem of large number cells in a sheet metal,the GPU parallel simulation calculation rate will be faster than

that by using the CPU's,as well as it has useful and practical value in solving the project problems.
