Optimization of hip implant done with SIMULIA Abaqus & SIMULIA Tosca

Posted by Christine Obbink-Huizer on Jan 28, 2020 9:45:00 AM

In the past, we have already given an example of optimizing a structure using Tosca. Now, I want to revisit this topic and focus specifically on geometry issues. I’ll explain how I obtained the geometry used for optimization, and also show how to get a 3D model of the optimized geometry, that can be used for further finite element analysis.

The example: a hip implant

Though we probably don’t always realize it, we use our hips a lot. After years of loading, they can become damaged and painful. In these cases, replacing the hip with an implant can be a solution. Here we are going to let Tosca design an optimized hip implant, as an example.

In the past, the reliability of some products were assured by keeping the mass of those relatively high. When computers started being a tool available for all, engineers began using them to calculate what is the likelyhood of failure. With this approach, weight of products was reduced and theirs reliability increased (or at least kept at the same level).

Non-parametric optimization of a clap skate using Tosca Topology

Posted by Christine Obbink-Huizer on Feb 6, 2018 9:56:34 AM

What do you do when you want to find a good design?

Have a brain storm session, come up with different designs, try each one out and choose the best one?

Or let the computer help you, by changing parameters such as dimensions and finding the design that matches the requirements best, possibly using Isight?

While such a parametric optimization is powerful in finding the best variation around a theme, non-parametric optimization can come up with a completely new theme: a new design concept. In this blog, we’ll take a look at non-parametric topology optimization using Tosca and Abaqus.

With the Winter Olympics coming up, being Dutch and in need of an applicable topic, we’ll use a Dutch invention; the clap skate (see Wikipedia) as example, and focus on the yellow part in the figure below.

First a regular Abaqus analysis is set up, and then Tosca is used to optimize the topology in this analysis.
