This paper reports an examination of the stresses and pressure fields set up at various cross-sections of a material during forging operation by the weighted residual finite element method. We present the numerical solution to the one-dimensional differential equation which describes the pressures and stresses exerted on a forging. In conducting the analysis, we split the blank into a finite number of elements and apply the Bubnov-Galerkin weighted residual scheme to obtain the weighted integral form; the finite element model is then developed from this weighted integral form which is solved to yield a three-parameter polynomial solution. Using series of examples, we show that the weighted residual finite element method is capable of accurately predicting the pressures and stresses in an open die forging operation.
