This article presents a detailed study on the potential and limitations of performing higher-order multi-resolution topology optimization with the finite cell method. To circumvent stiffness overestimation in high-contrast topologies, a length-scale is applied on the solution using filter methods. The relations between stiffness...

In this paper, we tackle the problem of selecting the radar node positions to provide an estimate of the target state vector with a prescribed accuracy. The topology optimization problem is formulated as selection of a fixed number of radar node positions from a set of available ones, where the radar observations are modeled by a general non...

Additively manufactured parts are often composed of two sub-structures, a solid shell forming their exterior and a porous infill occupying the interior. To account for this feature this paper presents a novel method for generating simultaneously optimized shell and infill in the context of minimum compliance topology optimization. Our method...

Topology optimization is a bio-inspired optimization method based on the growth of bones. With this method, the optimal material distribution with the minimal amount of material for a product can be defined. This could help engineers to create innovative lightweight designs and get rid of benchmark and pervious design on which current designs...

Additive manufacturing, colloquially known as 3D printing, is a production process that offers possibilities compared to conventional production methods. Current methods involve shaping or removing of material to create parts, where additive manufacturing adds material. Several industries have successfully implemented the technology showing...

Topology optimization is an automated design approach for structural applications that is gaining popularity in industry, including the aerospace sector. Resulting designs can be made suitable for traditional manufacturing techniques, although it is a technique that is particularly useful for non-conventional approaches such as additive...

This report has been written to serve as an introduction to the basics of GPU computing for mechanical engineers working in the field of structural optimization. In this work, the ability of GPUs to reduce the computation time of topology optimization problems is investigated. The programming paradigm of data parallel computing is introduced....

In this work, topology optimization is used to obtain optimal designs with minimal compliance as the objective. The checkerboard problem, refers to a resulting optimal topology where the material is distributed in regions of alternating solid and void elements. It has been shown that these regions emerge due to higher stiffness of the...

The ever growing population of human beings on earth introduces the challenge of providing affordable, sustainable energy for everyone. Emerging markets, such as China, India or Brazil, quench their thirst for cheap energy by fossil fuels and nuclear power. At the same time researchers from all over the globe warn the public of the advent of a...

Topology optimization is the process of optimizing both the material layout and the connectivity inside a design domain. The first paper on topology optimization dates back to 1904, when the Australian inventor Michell derived optimality criteria for minimum weight truss structures. In 1988 Bendsøe and Kikuchi published the pioneering paper ...

Advanced Cementitious Materials (ACM’s) are products with materials found in conventional concrete (cement, silica fume, sand, superplasticizer, and water) plus distinctive materials like fibers (steel, carbon) and quartz. The superiority of ACM’s in terms of strength, ductility, and durability marks it as high potential replacement of...

Topology optimization is increasingly used as a design tool in engineering. Within structural mechanics, most applications focus on statics. An extension to time-domain (transient) dynamics will have many useful applications, but this is currently hindered by high computational costs. The goal of this research is to reduce these costs by...

Free-form solar cells are cells of unconventional shapes (e.g. hexagonal, leaf-shaped etc). Their flexible shape adds to the aesthetics of the surroundings as well as allows to place them over objects where conventional solar cells might not fit. Evidently, these cells need to be efficient as well, and one of the important factors that...

Advances in additive manufacturing (AM) allow economical production of components with unprecedented geometric complexity. This offers exciting opportunities for innovative designs, and particularly topology optimization has been identified as a key technique to fully exploit the capabilities of AM. However, also AM involves manufacturing...

The potential of topology optimization to amplify the benefits of additive manufacturing (AM), by fully exploiting the vast design space that AM allows, is widely recognized. However, existing topology optimization approaches do not consider AM-specific limitations during the design process, resulting in designs that are not self-supporting....
