Have you heard the 1967 hit from the Box Tops, released later by Joe Cocker? Gimme a ticket for an aer-o-plane Ain’t got time to take a fast train Lonely days are gone, I’m a-goin’ home ….. Ok, that dates me – but check it out, it’s a great song. I should have subtitled this […]

## Topology Optimization (Part 3)

Topology optimization overview In the previous articles in this series, we looked at the various Topology Optimization methods used in commercial FE Analysis. In this article, we look at robust design solutions and methods used to align the final optimized design with available manufacturing techniques. Robust design under loading Figure 1(a) shows […]

## Topology Optimization (Part 2)

Topology optimization overview In the previous article in this series, we looked at the SIMP method of topology optimization in some detail. In this article, I look at two other important techniques; evolutionary methods and level set methods. A wide variety of methodologies are currently used within topology optimization, as it is a […]

## Topology Optimization (Part 1)

Topology optimization overview In Part 1 and Part 2 of this article I will dive a little deeper into the background of Topology Optimization and attempt to give some insights into what controls we can exert on the process to improve the relevance to our design goals. Figure 1 shows a typical topology optimization […]

## The “Three Topos” – optimization jargon explained

In an earlier article I explained the background to topology optimization. The piece prompted discussion in the various social media, including requests to clarify the differences between Topology, Topography and Topometry optimization. I will explain in the article what the different methods do. However, it is difficult to distinguish between the terms based […]

## What exactly is topology optimization?

Topology optimization is attracting a lot of fans! This month I review what topology optimization is and some of the practical issues it raises. Topology optimization is not new, the origins are usually attributed to Bendsoe and Kikuchi, reference 1, from 1988. By 2000 several FEA solvers had early versions. There is rejuvenated interest now […]
