Abstract
The determination of pattern dimensions using simulation is an inefficient trial-and-error process that requires several design iterations. In this study, the finite element inverse elastoplastic analysis is utilized to calculate the pattern geometry in a single iteration for a plastically deformed body. A simplified casting system is simulated to demonstrate the feasibility of the inverse method. An inverse simulation is performed first to calculate the pattern shape. This configuration is then used as the input geometry for a forward simulation, which is shown to successfully recover the original as-cast shape used for the inverse analysis. Through this sequence, the inverse deformation method is shown to be a viable technique for the determination of pattern allowances in production castings.
