## Simuleon FEA Blog

In this blog post, we will be looking into a different discretization method, available in Abaqus Explicit. This discretization method can prove to be really useful, in applications where gross distortions or large spatial displacements are expected to occur. A category of applications that can benefit from such a technology, are installations/decommissions of deep sea components, interacting with the seabed.

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.

Topics: DEM, Abaqus, CEL, SPH, meshless methods

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.

In most simulations, air and the pressure it exerts is not taken into account. There are situations thinkable, however, in which air plays an important mechanical role. An air gun is an example of this: compressed air exerts a force on a projectile, causing it to be propelled. In this blog, I will show how to model air using CEL, using a chamber in which air is compressed with a plug resting on it as an example.

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.

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.
