Controlling the maximum stress in structural stiffness topology optimization of geometrical and material nonlinear structures
TL;DR: In this article, a novel topology optimization method based on an extended Bi-directional Evolutionary Structural Optimization (BESO) method was proposed to maximize the stiffness of SGMN structures subject to both volume fraction and maximum von Mises stress constraints.

Topology optimization of structures subject to non-Newtonian fluid–structure interaction loads using integer linear programming
TL;DR: In this paper , a topology optimization design method for fluid-structure interaction (FSI) problems considering non-Newtonian fluid such as blood and polymer solution is proposed.

Topology optimisation: increasing the speed and reliability of design
TL;DR: In this paper, a comparison between the performance of a design created through evolutionary structural optimisation (ESO) and a baseline design modelled on a manually designed and successfully flow fuselage geometry, for different wing shapes, is drawn.
Journal ArticleDOI
Computer program for directed structure topology optimization
TL;DR: To compensate for the imperfection of traditional bi-directional evolutionary structural optimization, material interpolation scheme and sensitivity filter functions are introduced and the concept of distinguishing between active and non-active elements design is proposed.

Generating optimal topologies in structural design using a homogenization method
Martin P. Bendsøe,Noboru Kikuchi +1 more
TL;DR: In this article, the authors present a methodology for optimal shape design based on homogenization, which is related to modern production techniques and consists of computing the optimal distribution in space of an anisotropic material that is constructed by introducing an infimum of periodically distributed small holes in a given homogeneous, i.i.

Optimal shape design as a material distribution problem
TL;DR: In this article, various ways of removing this discrete nature of the problem by the introduction of a density function that is a continuous design variable are described. But none of these methods can be used for shape optimization in a general setting.

A simple evolutionary procedure for structural optimization
Yi Min Xie,Grant P. Steven +1 more
TL;DR: In this paper, a simple evolutionary procedure is proposed for shape and layout optimization of structures, where low stressed material is progressively eliminated from the structure during the evolution process, and various examples are presented to illustrate the optimum structural shapes and layouts achieved by this procedure.

A 99 line topology optimization code written in Matlab
TL;DR: It is shown that only 49 Matlab input lines are required for solving a well-posed topology optimization problem and by adding three additional lines, the program can solve problems with multiple load cases.
