How to strike the right balance between accuracy and solve times has been a major consideration for analysts since the inception of FEA.

In an ideal world we would include all parts and mesh each thread and fillet to ensure we have captured every detail of the model accurately. However, experienced analysts know that even with the luxury of modern-day processors, for many applications this is still a pipe dream. In reality, we tend to use our engineering judgement to omit certain parts or features and reduce mesh densities to reach acceptable but compromised solutions.

Luckily for us, Abaqus has a couple of “have your cake and eat it” solutions to this perennial problem in the form of substructures and sub-modelling. 

This FREE event on the 28th of February at our office in Den Bosch, NETHERLANDS, is meant for engineers who have some experience of Composites or FEA and would like to look at what is possible with simulation of composites performed by Abaqus FEA. The workshop is also suitable for engineers where ultimate structural performance is a critical product characteristic in their field. For example in areas of composite engineering such as marine, offshore, renewable energy, automotive, sports equipment and medical sciences.Structural Analysis - Composite behaviour.

What topics are discussed?

We’ve noticed that not everyone is familiar with the different ways in which we can help you if you have a simulation challenge. In this blog post, I want to go through the different options, explain what they are, for who they are available, and how to request this type of help.

In finite element analysis, traditionally we define the geometry at the start of the analysis and assume that while it may deform, the amount of material stays the same. For additive manufacturing, this is clearly not the case: material is continuously added. If we look at the thermal aspects of things, we also see a constantly changing problem: over time heat is added at different points in space; and the outer surface, where heat loss occurs, changes over time. Specific capabilities are therefore needed to efficiently set-up the simulation of problems that continuously change, such as the additive manufacturing process.

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.

Abaqus 2020 is out. In this webinar we’ll go through many of the modifications and new features, so you can determine where you can benefit from this release.

Have you ever wanted to do an interference fit in Abaqus/Explicit, import SolidWorks sldprt or sldasm files, define contact properties based on the materials of the underlying surfaces or simulate additive manufacturing? This, and more, is possible with Abaqus 2020.

In this blog post, we will be discussing about some of the most commonly used hardening laws that are available within Abaqus, and can be deployed whenever a metal’s plastic (inelastic) behavior and the nature of the applied load (monotonic, cyclic) becomes relevant in the modeling.

The “Introduction to Non-Linear Analysis Workshop” on the 31st of Jan, is a free event, held at our location in the Netherlands, for anyone who has some experience of simulation and FEA, but would like to look at extending the scope of the work they do. This workshop is an ideal way to understand what advanced simulation and SIMULIA Abaqus can offer, and find out how easy it actually is to perform a real world non-linear analysis.

This month’s webinar will cover meshing of native geometry in Abaqus. A short section on processing geometry to improve mesh quality will be followed by a discussion of the various meshing techniques available to the user. The webinar will conclude with a brief introduction to the tools available for working with non-native meshes in Abaqus.

In this blog post, we will be discussing about the translucency feature, that is there to help us enhance the results presentation of our fe analyses from within Abaqus Visualization.
