This paper is concerned with constraint handling techniques in GA integrated structural optimization. A modified version of Joines and Houck's [18] penalty function method is introduced and studied with respect to discrete optimization of truss structures. Three test cases are designed and numerically examined to reflect three distinct situations of loading and constraints. Certain recommendations are reached for penalty parameter values. Furthermore, the considered penalty function is reformulated to eliminate its shortcomings. The reformulated penalty function is also applied to the three test cases and the results are compared and fully discussed.

On efficient use of simulated annealing in complex structural optimization problems Hasançebi, Oğuzhan (Springer Science and Business Media LLC, 2002-01-01) The paper is concerned with the efficient use of simulated annealing (SA) in structural optimization problems of high complexity. A reformulation of the working mechanism of the Boltzmann parameter is introduced to accelerate and enhance the general productivity of SA in terms of convergence reliability. Two general and complementary parameters, referred as "weighted Boltzmann parameter" and "critical Boltzmann parameter," are proposed, Several alternative methodologies are suggested for these two parameter...
Structural Optimization Using ANSYS Panayırcı, H. Murat; Oral, Süha; Department of Mechanical Engineering (2006) This study describes the process of performing structural optimization using ANSYS. In the first part, the general concepts in optimization and optimization algorithms for different type of optimization problems are covered. Also finite element method is introduced briefly in this part. In the second part, important definitions in structural optimization are mentioned. Then the optimization methods available in ANSYS are explained with their theories. Necessary steps to perform optimization with ANSYS are d...
Von Mises' yield criterion and nonlinearly hardening rotating shafts Eraslan, Ahmet Nedim (Springer Science and Business Media LLC, 2004-04-01) A computational model is developed to estimate the stress distributions in rotating elastic-plastic solid and hollow shafts by the use of von Mises' yield criterion, deformation theory of plasticity and a Swift-type hardening law. An efficient numerical solution procedure based on the shooting method and Newton iterations is designed and used throughout this work to treat shafts with fixed and free ends. The results of the computations are verified by comparison with analytical solutions in the elastic rang...
A genetic algorithmfor structural optimization Taşkınoğlu, Evren Eyüp; Oral, Süha; Department of Mechanical Engineering (2006) In this study, a design procedure incorporating a genetic algorithm (GA) is developed for optimization of structures. The objective function considered is the total weight of the structure. The objective function is minimized subjected to displacement and strength requirements. In order to evaluate the design constraints, finite element analysis are performed either by using conventional finite element solvers (i.e. MSC/NASTRAN®) or by using in-house codes. The application of the algorithm is shown by a num...
A modular regularized variational multiscale proper orthogonal decomposition for incompressible flows Eroglu, Fatma G.; Kaya Merdan, Songül; Rebholz, Leo G. (Elsevier BV, 2017-10-01) In this paper, we propose, analyze and test a post-processing implementation of a projection-based variational multiscale (VMS) method with proper orthogonal decomposition (POD) for the incompressible Navier-Stokes equations. The projection-based VMS stabilization is added as a separate post-processing step to the standard POD approximation, and since the stabilization step is completely decoupled, the method can easily be incorporated into existing codes, and stabilization parameters can be tuned independe...
