... Abstract The structural design and additive manufacturing (AM) of cross-flow heat exchangers (HXs) are studied. A unit-based design framework is proposed to optimize the channel configuration in order to improve heat exchange performance (HXP) and meanwhile control pressure drop (PD) between...

... Abstract In structural design, expensive function evaluations can be replaced by accurate function approximations to facilitate the effective solution of multiobjective problems. In this paper we address the question: How can we solve multiobjective shape optimization problems effectively using...

... to build global approximations of computationally expensive computer analyses. Three structural design examples are presented to test the predictive capability of these metamodels for use in design optimization. The reported results confirm that these spatial correlation metamodels can produce sufficient...

... structural design problem. The algorithms first approximate the nonlinear constraint(s) and then solve the optimization problem. The accuracy of their results and their computational performance are then compared to identify a suitable algorithm for structural design applications. Using the identified method...

... The use of probabilistic optimization in structural design applications is hindered by the huge computational cost associated with evaluating probabilistic characteristics, where the computationally expensive finite element method (FEM) is often used for simulating design performance...
