Genetic Algorithms for Composite Laminate Design and Optimization
(Abstract) Genetic algorithms are well known for being expensive optimization tools, especially if the cost for the analysis of each individual design is high. In the past few years, significant effort has been put forth in addressing the high computational cost GAs. The research conducted in the first part of this thesis continues this effort by implementing new multiple elitist and variable e...
متن کاملA Distributed Genetic Algorithm with Migration for the Design of Composite Laminate Structures
(ABSTRACT) This thesis describes the development of a general Fortran 90 framework for the solution of composite laminate design problems using a genetic algorithm (GA). The initial Fortran 90 module and package of operators result in a standard genetic algorithm (sGA). The sGA is extended to operate on a parallel processor, and a migration algorithm is introduced. These extensions result in th...
متن کاملAn evaluation of local improvement operators for genetic algorithms
Genetic algorithms have demonstrated considerable success in providing good solutions to many NP-Hard optimization problems. For such problems, exact algorithms that always find the optimal solution are only useful for small toy problems, so heuristic algorithms such as the genetic algorithm must be used in practice. In this paper, we apply the genetic algorithm to the the NP-Hard problem of Mu...
متن کاملDesign using Genetic Algorithms -- Some Results for Composite Material Structures
This paper reviews an approach to design using Genetic Algorithms as applied to the domain of composite material structures. We first discuss the concept of a Genetic Algorithm (GA) and the role it can play in design, namely as an evolutionary search optimizer based on simulation results. We then discuss the composite structure design problem and how GA’s can be used for design in this domain. ...
متن کاملDesign of Composite Laminate Structures Using a Genetic Algorithm and Finite Element Analysis
This paper deals with the design of composite laminate structures using genetic algorithms and finite element analysis. Two examples are presented to show the flexibility of this tool in solving different kind of problems. The first case is a multiobjective problem where total weight and cost of an in-plane loaded plate must be minimized. Objective functions consisting on a weighted sum of thes...
