In order to investigate the flowing behavior of metal in rolling turbine blade steel with asymmetric pass,a FORTRAN program for calculating three-dimensional deformation was prepared.The program based on the principle of rigid-plastic FEM used 20-nodal isoparametric elements. The assumptions about initial velocity field and friction force were put forward, Through calculations,the flow of material and the distribution of velocity,strain and unit draught pressure were obtained.The experiment was performed with plasticine,lead and steel. The result of experiment and calculation are the same in egularity,and can be used in practical rolling process.
