Approximating Sinterklaas’ staff using Isight

Posted by Christine Obbink-Huizer on Dec 3, 2018 10:10:17 PM

Isight is probably best known for its capabilities to do optimization. However, this is not the only thing Isight can do. Isight also includes the option to create an approximation, for example. With this, a mathematical equation is fitted to the actual behaviour of one or more components. This approximation can then be used in other Isight models, so it is not necessary to run the actual component(s) each time. This can save a lot of time. In this blog, I’ll show how to make an approximation in Isight and what results data is available.

Fully coupled thermal structural analysis with Abaqus

Posted by Nikolaos Mavrodontis on Oct 29, 2018 4:59:38 PM

In this post, we will be showing some of the capabilities of Abaqus for performing fully coupled thermal-structural analyses. In particular, an exemplary geometry of a mountain bike's perforated disc together with the breaking pads (included in the caliper-not modelled) will be used to show some of Abaqus' conjugate heat transfer and multiphysics capabilities.

Join our online webinar: Hyperelastics with Abaqus FEA

Posted by Dolf Broekaart on Oct 22, 2018 10:37:10 AM

In this month’s webinar we will discuss how we can use Abaqus to accurately model hyperelasticity. This will take place on Friday 26th October.

Elastomers are used extensively within the world from cars to keyboards and shoes to ships. It is impossible to go about your day without interacting with a product that has a rubber component that is critical to its function.

However, for something so common it is surprisingly difficult to model accurately with FEA. We shall address this complexity and show how Abaqus can provide you with the tools needed to model your elastomeric components.

Automate boring postprocessing in Abaqus using python scripting

Posted by Christine Obbink-Huizer on Oct 5, 2018 1:58:40 PM

One of the benefits of doing simulations, is that it is easy to change various parameters to assess their influence on results. When doing this, often the same post-processing is needed for more than one analysis. Of course you can manually open each .odb, create the right images and save them, but this can be quite a lot of (boring!) work and the chance of making a mistake is definitely there. Therefore, it is often beneficial (and more fun) to create a script to do this automatically. In this blog, I will show how you can create a script to automate the creation of images using Abaqus.

Modeling Bolted Connections with Abaqus FEA

Posted by Nikolaos Mavrodontis on Sep 18, 2018 9:15:15 AM

In this blog post, we will be discussing about the different methods in modeling bolted connections with Abaqus FEA. At the last section of the post,we will be showcasing a bolted connection, incorporating a pretensioned bolt. Flanged connections are used extensively in most engineering disciplines. They provide a way of interconnecting  various (metallic, plastic etc.) components and their design is often critical for the strength of various components (e.g. bolt strength) and sealing of the assembly.

Join our hands-on workshop: From Testing to Finite Element Analysis for Rubbers with Abaqus

Posted by Dolf Broekaart on Sep 13, 2018 12:46:28 PM

 

On Friday the 26th or October, Simuleon and Elastomer Research Testing (ERT) are hosting the free hands-on workshop ‘From testing to Finite Element Analysis for Rubbers with Abaqus ’. In this unique co-hosted event Simuleon will present their solutions based on the SIMULIA portfolio and ERT will present their Rubber testing capabilities to gain material specifications for usage with SIMULIA Abaqus FEA.

Starting with a lecture session covering the essential concepts of advanced simulation for Rubbers, the course also gives the attendees the opportunity with our hands-on workshop, to model advanced phenomena such as non-linear elastic behaviour & material calibration, in-compressibility, element selection, shrink-fit & pressure penetration and other highly complex events with SIMULIA Abaqus.

4 Questions to ask when doing finite element analysis (or problem solving in general)

Posted by Christine Obbink-Huizer on Aug 29, 2018 5:15:03 PM

Let’s start with a problem:

“A ladder hangs over the side of a ship anchored in port. The bottom rung of the ladder touches the water. The ladder is 30 cm wide and 270 cm long. The rungs are 1 cm thick and the distance between them is 34 cm. If the tide is rising at a rate of 15cm per hour, how long will it be before the water reaches the top rung?”
