Modeling of steel fibre-concrete composites with Abaqus

Posted by Nikolaos Mavrodontis on May 14, 2019 9:18:53 AM

In this blog post, we will be discussing about steel fibre reinforced concrete (termed as SFRC) and will be showcasing a way (more modelling ways do exist)  to model the interaction between the steel fibre (reinforcement) and the concrete (matrix).

Introduction to Non-Linear Analysis - Join our Abaqus Workshop - 24 May 2019

Posted by Dolf Broekaart on Apr 30, 2019 9:07:49 AM

The “Introduction to Non-Linear Analysis Workshop” on the 24th of May, 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.

Join our online webinar: Metal inelasticity in Abaqus

Posted by Dolf Broekaart on Apr 24, 2019 3:39:01 PM

In this webinar we will look at some of the characteristics of metal’s inelastic behaviors under monotonic and cyclic loading and how these behaviors can be modelled in Abaqus with the use of inelasticity models. In specific, the bilinear elastic-plastic, kinematic and isotropic hardening plasticity models will be discussed.

Information about the modelling of damage will also be provided for metals experiencing a ductile type of failure.

Creating an axisymmetric model from 3D geometry in Abaqus

Posted by Christine Obbink-Huizer on Apr 23, 2019 9:47:14 AM

Geometry is often drawn in 3D, also when it is axisymmetric. The analysis will be much faster when making use of the axisymmetry. In such cases, we need to get an axisymmetric cross-section out of a 3D model. In this blog I will show a way to do this with Abaqus. The main idea is to create a sketch on a cross-section of the part and project the relevant edges to this sketch. This sketch is saved and used to create a new axisymmetric part. This isn't the only way of doing it, but at least it gives an idea.

Introduction to Optimization for Abaqus - Join our Tosca & Isight Workshop - 26 April 2019

Posted by Dolf Broekaart on Apr 16, 2019 9:14:22 AM

The “Introduction to Optimization for Abaqus Workshop” is a free event for anyone who has some experience with Abaqus and would like to explore the possibilities of optimization. Both non-parametric topology optimization using Tosca and parametric optimization using Isight are discussed, focusing on the optimization of problems using the finite element code Abaqus.

Submitting Abaqus commands through the command window

Posted by Christine Obbink-Huizer on Apr 2, 2019 9:56:39 AM

Some time ago we posted a blog on How to submit and monitor Abaqus jobs through command window. I would now like to revisit this subject, go into a few additional commands and options, including different Abaqus versions and the findkeyword and fetch utilities, and look in a bit more detail to the abaqus commands

Join our online webinar: Meshless Methods in Abaqus

Posted by Dolf Broekaart on Mar 21, 2019 1:45:46 PM

In this webinar we will look at three of these modelling techniques; SPH (Smoothed Particle Hydrodynamics), CEL (Coupled Eulerian Lagrangian) and DEM (Discrete Element Modelling).  For each technique the webinar will walk through how they are implemented in Abaqus and consider practical examples demonstrating when each technique is most appropriate. 

This capability is available without the need for extended tokens and therefore may be of interest to anyone already familiar with Abaqus.

Geometry Operations in Abaqus FEA software

Posted by Nikolaos Mavrodontis on Mar 5, 2019 9:51:00 AM

In this blog post, we will be discussing about geometry operations on 3d models, that have been imported in Abaqus as a neutral geometry format, or via the Associative Interface (if you are interested more about the AI, have a look at an earlier blogpost). We will be showing the different tools available in order to detect geometry issues in the imported model (Geometry diagnostics tool, accessible via the Query tool) as well as fix geometry issues from within Abaqus (Geometry Edit toolset, accessible through the Part module in Abaqus).

Units in Abaqus

Posted by Christine Obbink-Huizer on Feb 25, 2019 10:16:00 AM

In this blog, I want to discuss units in Abaqus. On one hand, I can be short on it: we can choose what we like, as long as it is consistent. On the other hand, this is a common source of mistakes. Therefore I want to go into a bit more detail.
