Abstract: A simplified 8-node element was devised by taking one layer of elements in the direction normal to a plane of symmetry and assuming that the element sides which are initially normal to the plane remain normal during deformation. Using the simplified elements, the three-dimensional analysis for the FM forging method was performed. The excellent agreement between experimental and computed dimension values and configurations of specimens has been seen. By comparison of the computed results of FM method and conventional flat forging, the better effect in FM method to consolidate internal cavities at the central part of block has been proved. The optimum of the values of geometrical parameters for FM method was proposed.
