1-way coupling & 2-way coupling in FSI problems
Forums
Hi all,
any one know what is difference between "1-way coupling" and "2-way coupling" in FSI problems?
Is there any difference between above methods and "weak coupling" and "strong coupling" methods ?
PhD Structural Vibration and Analysis/Computational Mechanics
PhD Scholarship: Structural vibration analysis and computational mechanics
One scholarship is available for a PhD student to pursue research in the School of Engineering at the University of Waikato towards the development of a general analytical procedure for vibration analysis of complex structures. In modelling solid bodies with voids, we will consider treating the voids as embedded negative bodies.
The successful candidate will work with:
Professor Sinniah Ilanko and Dr Yusuke Mochida (University of Waikato, New Zealand)
FEAP - user element subroutines

Hi all,
my question is about the history data storage in FEAP.
I am writing element subroutine (elmt01) in FEAP 8.3 for a history dependent problem (crystal plasticity).
I have written the stiffness
matrix subroutine (stiff01), but it needs the data from the previous
solution steps (previous strains, stresses, plastic strains, dislocation
densities .... nh1,nh2=30 per point).
moving heat source
how to do moving heat source , without using subroutines
ABAQUS Johnson-Cook damage model
Forums
The constants of the Johnson–Cook fracture criterion D1, D2 ，D3，D4 and D5 are identified from tensile tests or torsion tests, but I don't kown about the specific procedure to obtain the constants. sigma*=sigma(m)/sigma,sigma(m) is the average of the three normal stresses,sigma is the von Mises equivalent stress. The sigma （stress）obtained from the tests is corresponding to the which sigma in the equation. Thanks for your information 。
Implementation of p-p Interactions in Molecular Dynamics Simulation
Dear All,
I want to simulate polymer system that have pi-pi interaction between
chains and reinforcements. I know there is no implemention of pi-pi
interaction in lammps.
So, Is there another method to consider pi-pi interaction in lammps? or
I can't simulate these system by lammps.

Abaqus equivalent of MSC.Marc's element #144
Hi All,
Any idea what would be Abaqus equivalent of Marc's rebar element #144? Thanks in advance.

Abaqus Quasi-static induced numerical damping
Forums
Choose a channel featured in the header of iMechanica
The Quasi-static method for dynamic problem in Abaqus should be carefully used, because it will automatically induce the numerical damping in your calculation.
This method is very conservative, approximately it will introduce 5% numerical damping (damping ratio).
This method is helpful for contact problem and for convergency. But be careful when using it.
Hi All!
My problem is quite simple:
I need to change (add arguments) to a inp file, then submit the inp file
for analysis and finally to
read some results from the odb file.
I choose to use python (not the PDE provided by abaqus CAE but the
general python GUI). I’m sure this choice has consequences, perhaps the
import abaqus won’t work? This could bypassed if I run my code using abaqus python in the command window.
