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.

NANOENGINEERED COMPOSITES: Properties, modelling and applications

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!
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?
As part of the 13th US National Congress on Computational Mechanics to be held in San Diego, CA, on July 26-30 2015, it is our pleasure to invite you to submit an abstract to the Symposium “Advances in Computational Methods for Heterogeneous Materials”.
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.
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. As the automotive industry is mainly familiar with metals and plastics, a lot of research is being spent on the mechanical response of composites under fatigue and impact loading, and on developing new design methodologies for these "new" materials.
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:
"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.
