On the 19th of January at 11.30 a.m. we will host our Abaqus 2017 Whats New Webinar. In this webinar, we will discuss the new release functionality within Abaqus 2017.
This blog focusses on the things that could be useful when considering using, buying or leasing Finite Element Analysis Software. These tips can be used for both future FEA users as well as managers and decision makers who are thinking about starting to use FEA Software, or think about upgrade and expand their existing FEA Software.
For this blog, the following example is used.
Topics: FEA software
This simulation is performed with SIMULIA Abaqus using the CEL - Coupled Eularian Lagrangian technique. Internal pressure is applied to the CEL domain and comes to a burst.
When performing a finite element analysis many modelling choices must be made. One of them is the choice of material properties. This can have a big influence on the outcome of the simulation. In many cases some material properties are known, for example in a data sheet. These normally do not directly correlate to the parameters required by Abaqus. When not all the required material properties are known, experimental data must be obtained. Based on this data, a material model and material parameters must be defined.
On the 25th of November at 11.30 a.m. we will host our Post-processing – Part 2 in Abaqus Webinar. In this webinar, we will continue to look at advanced techniques available in Abaqus/Viewer such as animations, results computations and user-defined field outputs. We will also look at other ways of post-processing the analysis results such as using the .dat file. Finally, we will present the new features that will be available in Abaqus/Viewer 2017.
This video shows a pumping impacted to a wall, including damage failure and conversion to SPH particles.
This blog shows how we performed a drop test for a Polyethylene 100 liter Fueltank containing fluid with SIMULIA Abaqus FEA Software. The goal of this analysis is to predict the possible material behaviour and failure that will lead to leakage.
This example involves a fluid-filled plastic tank falling from a height of roughly 15 meters onto a flat, rigid floor. The tank as shown in the pictures below is made of high-density polyethylene with a wall thickness of 5 mm everywhere. The tank is filled almost completely (about 90%) with water. A realistic simulation for the tank must account for both the exterior forces on the tank from the floor impact, as well as the interior forces of the water pushing against the walls of the tank. Resulting stresses and strains in the tank will be used to determine its structural feasibility.
This blog shows how we performed an Indentation Force Deflection (IFD) test for a Polyurethane Foam Sample, following the ASTM D 3574. The goal of this analysis is to show the Force behaviour over time during indentation.
In this blog we will focus on a problem that happens when working with input files. Not exclusively but it is often encountered when performing geostatic finite element analysis (FEA). Briefly, the problem is that the analysts work with finite element models where no geometry is available but only a mesh. Working without geometry brings an important limitation: re-meshing and therefore local refinement is not possible.
But why would we need re-meshing in the first place?
Meshes next to a fault might be fine enough to capture the necessary detail. However, meshes away from the region of interest do not need to have the same level of refinement. If our domain extends through a couple of kilometres we would have extremely large meshes.
