Abstract
Automatic differentiation tools, ADIFOR [1](Bischof, C. H. and Griewank, A., Proc. 4th AIAA/USAF/NASA/OAI Symposium on Multidisciplinary Analysis and Optimization, Cleveland, OH, pp. 433–441, 1992), are incorporated into a finite element-based structural analysis program for shape and non-shape sensitivity analysis of structural systems [2, 3](Arora, J. S. and Haug, E. J., Applied Optimal Design, John Wiley and Sons, Inc., 1991; Hafta, R. T., Gurdal, Z. and Kamat, M. P., Elements of Structural Optimization, Kluwer, 1990). The entire analysis and sensitivity procedures are parallelized and vectorized for high-performance computation [4, 5](Agarwal, T. K., Storaasli, O. O. and Nguyen, D. T., Proc. AIAA/ASME/ASCE/AHS 31st SDM Conference, Long Beach, CA, 1990; Qin, J. and Nguyen, D. T., Proc. AIAA/ASME/ASCE/AHS 34th SDM Conference, LaJolla, CA, 1993). Small-scale examples to verify the accuracy of the proposed program and a medium-scale example to demonstrate the parallel-vector performance on the Cray-C90 processors are included in the paper.
