Material interpolation schemes in topology optimization

TL;DR: In this article, the authors analyze and compare the various approaches to this concept in the light of variational bounds on effective properties of composite materials, and derive simple necessary conditions for the possible realization of grey-scale via composites, leading to a physical interpretation of all feasible designs as well as the optimal design.

Morphology-based black and white filters for topology optimization

TL;DR: In this article, the physical stiffness of an element is based on a function of the design variables of the neighboring elements, and a new class of morphology-based restriction schemes that work as density filters is introduced.

Generating optimal topologies in structural design using a homogenization method

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.

Optimization of structural topology, shape, and material

TL;DR: The method presented in this book has been developed by Martin Bendsoe in co-operation with other researchers and can be considered as one of the most effective approaches to the optimization of layout and material design as discussed by the authors.

A new Approach to Variable-Topology Shape Design Using a Constraint on the Perimeter

TL;DR: The perimeter method as mentioned in this paper allows the designer to control the number of holes in the optimal design and to establish their characteristic length scale, thus eliminating the need for relaxation, thereby circumventing many of the complexities and restrictions of other approaches to topology design.

An optimal design problem with perimeter penalization

TL;DR: In this paper, the optimal design problem of finding the minimal energy configuration for a mixture of two conducting materials when a perimeter penalization of the unknown domain is added is studied and it is shown that in this situation an optimal domain exists and that, under suitable assumptions on the data, it is an open set.
