Multiscale Modeling Consortium
The Multiscale Modeling (MSM ) Consortium has been set up by a an interagency modeling and analysis group (IMAG ) comprised of staff from 17 NIH components, four NSF directorates, two Department of Energy (DOE) components, five Department of Defense (DOD) components, the National Aeronautics and Space Administration (NASA), the United States Department of Agriculture (USDA) and the United States Department of Veterans Administration(USDVA) to provide a forum for discussion on matters related to MSM research and

Modeling Metal forming in Abaqus...
I'm currently working on my master thesis which is in the area of metal
forming simulation...
I have one question,,, when adding material plasticity in Abaqus using the
power law...
to what limit shall i go in the tabulated form is it to 100% plasticity or
to the maximum strain the material can take...
in other word,,, if the power law is: σ =250*εp^0.123...
shall i inter the values till at σ=250, ε=1... or shall i stop at let say ε=0.25...
Regards,,,

RECENT DEVELOPEMENTS ON THE USE OF FDM IN ELASTICITY ANALYSIS
Computational field of solid mechanics is mostly dominated by FEM. This is a well known topic.
But is it that FDM (finite difference method) has no chance of surviving
in solid mechanics?
What are the present developments in the use of FDM in case of elasticity analysis of solid body?
I would like to mention some of the recent research works on this topic here.....
Recently a new mathematical model has been developed by Prof. S. Reaz Ahmed and his students known as the "displacement potential approach".
Ductile Fracture Simulation
Hi,
I am simulating ductile fracture through uniaxial tensile test. The material is Aluminum Alloy. Dogbone specimen is simulated to get Equivalent Strain Vs Stress Triaxiality & Equivalent Strain Vs Lode Angle plots. The evolution of Stress Triaxiality & Lode Angle must be 1/3 & 1 respectively over time or with Equivalent Strain. I have marked few time history solid elements in the rupture zone of model. The problem is, Triaxiality and Lode Angle is different for different time history elements.
Abaqus Script Manual/Tutorial
I have written a introduction manual/tutorial on Abaqus Scripting. I got some good feedback from my colleagues. Therefore, I would like to share the manual.The manual should give a short introduction (it will not take more than one hour) to Abaqus script in Python.
You can find the manual here:
Via the same link you can also find more information on the connection between Matlab and Abaqus
Good luck!
