Two new methods are available in Abaqus to couple analyses performed at different scales: mean field homogenisation (MFH) and FE-based Representative Volume Element (RVE). The objective is to predict the mechanical response of a structure using data from a smaller scale. These methods are particularly useful when studying complex materials or structures such as composite materials or lattice structures.

In this webinar, we will present the two methods:
- MFH, that uses an analytical calculation to describe the relationship between the scales and
- FE-RVE, that uses a FE model of the microstructure.

We will also look at the micromechanics plug-in that facilitates the generation of FE-RVE models and calculates the homogenised properties of a material that can then be used at the macro scale.

Sometimes you may wish to simulate a process where various parts interact with one another. In such cases it is often impossible to rely on predefined loads and boundary conditions, since the exact points of contact are dependent on the solution. Including contact in your simulation can be a more realistic way to represent loadings.

Abaqus provides a wide range of mechanical models and numerical methods for contact. We will begin this month’s webinar with an overview of these capabilities, considering how to select the best options for a given problem. We will then move on to some challenging example problems and investigate how advanced features of Abaqus contact can help convergence and ensure you obtain realistic solutions.

This webinar will provide an overview of some of the capabilities within fe-safe, looking at the more general functionality within the software and showing how this fits in your current simulation process, focusing on the ease of use of the platform.

The webinar will then continue on to discuss the capabilities of weld modelling using Verity and finish by focusing on the fundamental differences between stress and strain based fatigue.

Over 5 weeks in a 2 hour session each week, from the 8th of May till 5th of June, Simuleon will hold an Online Training with live broadcasting. The training is called "Abaqus for Composites".

How to get the best from them & how to avoid problems

This month’s webinar relates to shell and beam elements.  It will cover the benefits of using these types of elements for particular problems, and when they should not be used.  The different types of shell and beam elements will be discussed, along with modelling techniques and problems and work arounds.

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. 

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.

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 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).

Problem solving and simulation within the Oil and Gas industry use approaches that are generally familiar to other more mainstream mechanical engineers, but often require the use of specific, often codified, processes and tools.

This webinar will look at some of the tools that are available within Abaqus that allow an in-depth insight into the behaviour of systems in ways which conform to accepted standards in Oil & Gas industry. These include:
