Tapered rectangular boxes of aluminum and mild steel were formed using the hydromechanical deep drawing process. The experiments are described and discussed, and the process is analyzed numerically using the explicit finite element method. The numerical results are discussed and compared with the experimental results. Blanks of octagonal shape and circular shape and of various dimensions are simulated and compared, suggestions being made on this basis. The failure modes of local thinning and body wrinkling occurring in the experiments are predicted. (C) 2000 Elsevier Science S.A. All rights reserved.
