摘要：

In this paper a particularization of forging process is presented, studying the deformation of a ring specimen. Plastic forming is performed by means of the Upper Bound Theorem and the model of Triangular Rigid Blocks to calculate the minimal charge needed to deform the part. The establishing the part to deform an annular geometry is determined by the so-called Ring Compression Test under its canonical configuration, that allows assimilating to a plane strain process. A new perspective to calculate the neutral plane (radius at which the workpiece material flows in opposite directions) is proposed, a basic element in the solution of the problem.
