Abstract

Parallel processing of forging simulation by upper bound elemental technique B. Song", B. Parsons^ F.H. Osmaif , A.N. Bramle/ Nanyang Technological University, Nanyang ^Department of Mechanical Engineering, Queen Mary and Westfield College, Mile End Road, ^Department of Mechanical Engineering, University of Bath, Claverton Down, Bath 7,47, ABSTRACT Presented in this paper are parallel algorithms developed for simulation of forging and extrusion type operations on a Distributed Array Processor (DAP) by Upper Bound Elemental Technique (UBET). Particular attention is paid to the parallel solution of UBET by optimization techniques. The UBET approach, its formulation, and suitable parallel algorithms are presented, and discussions are made on the parallel algorithms for the UBET calculation and optimization processes. Results of the parallel algorithms on the DAP are evaluated in comparison with that of a serial approach on a mainframe computer. INTRODUCTION The Upper Bound El
