Topology optimization approaches

Structural and Multidisciplinary Optimization, 2013
Topology optimization has undergone a tremendous development since its introduction in the seminal paper by Bendsoe and Kikuchi in 1988. By now, the concept is developing in many different directions, including “density”, “level set”, “topological derivative”, “phase field”, “evolutionary” and several others. The paper gives an overview, comparison and

Topology optimized microbioreactors

Biotechnology and Bioengineering, 2010
AbstractThis article presents the fusion of two hitherto unrelated fields—microbioreactors and topology optimization. The basis for this study is a rectangular microbioreactor with homogeneously distributed immobilized brewers yeast cells (Saccharomyces cerevisiae) that produce a recombinant protein.

Metric-topological–evolutionary optimization

Inverse Problems in Science and Engineering, 2011
This article shows a novel approach for optimization and inverse problems based on evolutionary computation with the aim to satisfy two opposite requirements: exploration and convergence. The proposed approach is particularly suitable for parallel computing and it gives its best both for multimodal problems and for problems in which bad initializations

Topology Optimization with Superelements

AIAA Journal, 1996
The superelement method was employed for finite element analysis. The target panel was modeled as the residual structure and the rest as one big substructure.

Continuum Topology Optimization

10th AIAA/ISSMO Multidisciplinary Analysis and Optimization Conference, 2004
Many shortcomings of the existing topology optimization approaches are reported because the number of design variables is too large and design change is limited by the setting of the initial domain that absolutely inf luences optimization results although much improvement is under way.

Topology Design Optimization

2020
In this chapter, a topology optimization algorithm based on the topological derivative concept combined with a level-set domain representation method is presented. The model problem is governed by the elasticity system into two spatial dimensions. The topological asymptotic expansion of a tracking-type shape functional, associated with the nucleation ...

Adaptive topology optimization

Structural Optimization, 1995
Topology optimization of continuum structures is often reduced to a material distribution problem. Up to now this optimization problem has been solved following a rigid scheme. A design space is parametrized by design patches, which are fixed during the optimization process and are identical to the finite element discretization.

Multidiscipline topology optimization

Computers & Structures, 1997
Abstract Topology optimization is used for determining the best layout of structural components to achieve predetermined performance goals. The density method which uses material density of each finite element as the design variable, is employed. Unlike the most common approach which uses the optimality criteria methods, the topology design problem ...
