Design and Optimization of Axial, Mixed-flow and Radial Turbines for Turbochargers Webinar

The turbocharger efficiency has a direct effect on the fuel efficiency of the engine. However in many turbocharger turbine applications it is becoming increasingly difficult to improve the turbine efficiency with conventional design methods.

Extract Consistent Mass Matrix for Solid Element - ABAQUS

I need to extract the consistent mass matrix of a solid element, the thing is every time I use *MATRIX GENNERATE  it gave me the lumped mass matrix which is a reduced version of the consistent mass matrix. However, if I use a beam element, I just need to print out next to *Beam Section, Lumped = NO to give me the consistent mass matrix but only this option is applicable for beam element which will not be helpful model cause I need a solid element.

Question about calling subroutine to get strain and stress

I am writing a subroutine DFLUX, the FLUX(1) is dependent on strain and stress. But I don't know how to get the strain and stress. I use SPRINC in the code but it seems to be wrong.

The equation for the problem is

Postdoctoral position on: Identification of elastic microstructures from full-field measurements - CNRS & Aix-Marseille University France

A one-year postdoctoral position is available at the Laboratory of Mechanics & Acoustics, CNRS & Aix-Marseille University, France.

The project focuses on image-based identification problems for physical quantities of interest in solid mechanics within the framework of optical measurement methods for complex manufactured materials. The guideline objective is to develop an identification framework for multiscale, heterogeneous and anisotropic media.

Multiscale modelling of load transfer in grephene laminates

Hi everyone,

                     First  little bit of background over my model.

My model is 3d,deformable solid extrude and consist of grephe flakes  each flakes depth is 0.33 nm and length we can input,We can input the total   box size in nm of layers in that box...and the size of flakes...and the layers are generated automatically with no pattern.And Both side are supported with support.And one side is fixed and another is provided with displacement load.The element is 4 node linear terahedron.



Dear ALL,

Does anyone here has an experience carry out  FE analysis for a part[bracket] which was deformed plastically during cyclic loading test.

I'm now working to resolve this issue when a bracket was fail to withstand the constant loading of 500N during cyclic test. It was reported fail at ~3800 cycles which was less than target.

How to model random dispersion of MWCNTs in epoxy resin

Dear All,

I want to start some research on the Multi walled Carbon nano - tubes/ Epoxy resin.

In the begining I need to model a random dispersion of MWCNTs in epoxy resin in  the ABAQUS.


Can any help me in this problem.


Thank you in advance.

want to start some research on the Carbon nano - tubes. In the begining I need to model a CNT in the ABAQUS.

Concrete block under thermal load

Dear all,

I am new to abaqus and trying to analyze the thermal analysis on a concrete block of size 0.15 x 0.15 x 0.15.

The surface heat flux of magnitude 100 that I am giving is only from one side and NOT having any boundary conditions.

If I choose steady state condition then I get an error as "Time increment required is less than the minimum specified".

Also I cannot define time period. I want the nodal temperature of concrete subjected to thermal load from one side for 24 hours of heating at 100oC.

Please help!

Using different types of stress rates in ABAQUS UMAT

Dear friends,

As you maybe know, ABAQUS uses the Jaumann or Green-Naghdi stress rate for large deformation analysis. Recently i found some refrences that show these stress rates leads to major errors for some special cases. Now my question is, how can I change the stress rate used  in analysis process using ABAQUS UMAT?

What is the Mechanical properties of Spandex?

   Hello everyone I'm new here, Hope you can help me!

I was looking for an elastic material and I found a material called Spandex or Lycra(its trade name) I tried to find its mechanical properties on internet, but could not find specific calculation such as its Yielding stress and its modulus of elastisity(E), the most important thing i need is to find the maximum force or stress that it can stand.

Thank you.


Postdoc position on multi-scale modelling of composites vibration response @ Ghent University (Belgium)

Nowadays, there is an increasing interest to use composite materials in automotive applications, in particular the use of fibre-reinforced plastics (carbon or glass fibres in a polymer matrix) is widely considered. The use of lighter materials, and hence a reduced fuel consumption, can be one of the possible solutions for reduced CO2 emissions.

PhD position on multi-scale modelling of fatigue damage in composites @ Ghent University (Belgium)

The core idea of this project is to develop a consistent multi-scale modelling framework for fatigue damage in unidirectionally reinforced composites. Three scales are distinguished:

Postdoc on FE simulation of 3D printed cellular structures @ Ghent University (Belgium)

"3D printing" is a popular term for the layerwise manufacturing of metals or polymers with a printing head, that builds up the component with droplets of molten polymer or metal into a 3D shape. The geometries that can be realized with this technique, can be very complex, and this with a minimum of material usage, because no material has to be milled away. Further, very lightweight materials can be achieved. Flanders region plays a leading role in Europe in this 3D printing sector, with important industrial players such as Materialise, Layerwise and Melotte.

PhD position in Mechanical Engineering available (EU/UK applicants only)

In many areas of engineering, materials and structrures are subjected to deformation at high rates (e.g., impact, crash, blast). Therefore, it is essential for design engineers to have reliable mechanical models to predict the behaviour of the materials in such applications. It is proposed in this project to extend the Virtual Field method to high velocity loading conditions where inertial forces affects significantly the deformation mechanisms of the material under dynamic loads.
