The objective of this paper is to present efficient domain decomposition methods for handling large-scale shape and topology optimization problems. The methods presented in this work are based on a two-level domain decomposition implementation which is a combination of a primal and a dual domain decomposition method. This method proved to be very efficient in the case of reanalysis problems, which arise very often in structural optimization problems. The numerical tests demonstrate the computational advantages of the proposed methods which become more pronounced in parallel computing environment.Keywords:Structural OptimizationDomain Decomposition MethodsPreconditioned Conjugate Gradient MethodReanalysis Problems FiguresReferencesRelatedDetailsCited By 4Probabilistic Thickness Requirement of CFRP Plates Bonded to Reinforced Concrete Bridge DecksA.
