Abstract: The adjoint method has been used in structural optimization to compute sensitivity coefficients of cost and constraint functions with respect to design parameters. The adjoint method involves the calculation of an adjoint ...

Abstract: Probability-based optimal design of structures is presented. The emphasis here is to develop a practical approach to optimal design given random design parameters. The method is applicable to ...

Abstract: A Lagrangian approach to design sensitivity analysis is presented. The final equations obtained by the Lagrangian approach are identical to those obtained by the adjoint method reviewed in the literature. The difference ...

Abstract: The problem of designing mechanical systems or components under uncertainty is considered. The basic idea is to ensure quality control at the design stage by minimizing sensitivity of the ...

Abstract: A methodology for complete automation of the conventional highway bridge design for minimum cost is presented. To make such an automated process practical and cost‐effective, efficient interface of three tasks—finite‐element ...

Abstract: A general formulation to obtain the analytical expressions for the sensitivity of the acoustic power radiated by a vibrating structure to one of its design variables is described. The formulation, ...
