摘要
The aluminium sheet rolling is studied by using three dimensional elastic-plastic finite element method (FEM) based on considering both material and geometric non linearity.Three dimensional distribution of the stress and deformation are given on the VAX11 / 780 computer. The spread deformaton of the workpiece is analyzed by means of the moire method.The calculation results are compared with experimental results of the moire and agreement is well.
