Abstract:
The aluminum
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 deformation 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.
Key words:
