5. Iterative methods for design sensitivity analysis

Author

Ashok D. Belegundu and B. G. Yoon

Subjects
Mathematical optimization, Iterative method, Numerical analysis, Aerospace Engineering, Applied mathematics, Perturbation (astronomy), Stress distribution, Triangular element, Finite element method, Eigenvalues and eigenvectors, Mathematics
Abstract

A numerical method is presented for design sensitivity analysis, using an iterative-method reanalysis of the structure generated by a small perturbation in the design variable; a forward-difference scheme is then employed to obtain the approximate sensitivity. Algorithms are developed for displacement and stress sensitivity, as well as for eignevalues and eigenvector sensitivity, and the iterative schemes are modified so that the coefficient matrices are constant and therefore decomposed only once.
