July’s webinar will present the analysis types available in Abaqus, for evaluating the structural response under buckling, post buckling and collapse.

Buckling is the sudden collapse of a structural member under axial compressive loading. The importance of accurately predicting buckling loads during design is paramount, since these loads are on most occasions lower than the ultimate compressive loads of the particular member. The non-linear character of this failure type, imposes a modelling and convergence challenge.

The “Introduction to Non-Linear Analysis Workshop” on the 26th of June is a free event 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.

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.

In this blog post, we will be showcasing a fully coupled fluid structure interaction (FSI) analysis, of a peristaltic roller pump. This study will focus on assessing the performance of a peristaltic pump, under operation. This co-simulation analysis, will solve for both the structural and fluid domains' unknown quantities, during 1 revolution of the rotating mechanism of the pump.

This is an example of a challenging application, in which numerical modelling and computer simulations can provide a lot of insight and value.

The aspects we want to evaluate in this digital model are; determining the volume flow-rate for a given rotation speed, assessing contact stress areas on the tube, and determining the torque output for the given rpm.

The “Introduction to Non-Linear Analysis Workshop” on the 29th of May is a free event 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.

Today I have came across a very inspiring video.

It contains a lecture of Dr. David Hibbitt, founder of the Abaqus software, held on 24th of may 2019 at MIT, department Civil and Environmental Engineering. The lecture was called; "ABAQUS and its market:  evolution of an engineering simulation software venture."

If you have an hour left during the day / evening, sit back, relax and watch this inspiring lecture, where Dr. David Hibbitt goes through the actual start-up phase of the Abaqus company until today.

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".

In this blog post, we will be discussing the differences between the kinematic and distributing constraints in Abaqus. The differences between these types of constraints will be highlighted in an example model.

Introduction and Usage

Surfaced based coupling constraints are used in Abaqus for the following purposes:

These days, unfortunately the whole world is facing the dramatic effects of the current Corona/Covid-19 pandemic. Like any other global business currently, this is also affecting our local business and how we interact with our customers and software users. Our company has taken the following measures following the advice of our National RIVM institute.
