Abstract

Finite element method is used as a design tool in the prediction of process parameters for superplastic metal forming processes. The method is used in the design of various plane strain and axisymmetric components. The effect of varying die radii and die friction are studied in the forming characteristics of a simple pan. The cone test used for the mechanical characterization of superplastic materials is simulated. A complex component typically used in the aerospace industry is analyzed and the output pressure-time loading and the resulting thickness distributions are determined.
