Abstract
Internal defects in the cross wedge rolling process can lead to the catastrophic failure of products. Using specialized experiments and the explicit dynamic finite element method, this work investigates the mechanisms of void generation and growth for the cross wedge rolling process. Based on the combined numerical and experimental results, the morphology of void generation is determined as a function of workpiece material and three primary parameters in cross wedge rolling process : the forming angle, α, the stretching angle, β, and the area reduction, ΔA. In addition, through the definition of a non-dimensional deformation coefficient, ε, a method for predicting the likelihood of void formation is subsequently ascertained and discussed with respect to CWR tooling design and operating conditions.
