review text: A three-dimensional finite element analysis of forging of blocks with continuous curved dies is carried out on the basis of a rigid-plastic material model. A method of imposing velocity boundary conditions on a three-dimensionally curved surface is proposed using a skew boundary condition. The frictional boundary condition is considered on a continuous curved surface. The initial velocity field is generated by introducing the assumption of linear viscous material. Forging of square blocks with hemispherical punches of various radii is simulated. Experiments are carried out to check the validity of the formulation. The comparison between computation and experiment shows good agreements in forging load as well as in deformed configuration.
