Hello,
I was wondering if it is possible to apply a tie constraint in a particular step in Abaqus ( while running a multi step analysis).
My simulation is a 3 step process. The first step involves the assembly of 2 concentric cylinders, by making a plug move through the inner tube, expanding...
Hello,
I'm trying to model a tube drawing process, where the draw plug moves through the inner surface the cylinder along its length, thereby expanding the tube. My model runs in abaqus explicit, but takes forever to converge. I'm surprised that an axisymmetric model takes this long. Below is...
Ok I faced a similar issue a while back where I had to input residual stresses from a static analysis into a fully coupled thermal stress model. I figured that there isn't a way to specify initial residual stresses in Abaqus withouyt using the subroutine. this is what i did
Step1 : Fully...
What is the reference temperature used by Abaqus in the event that an initial temperature isn't specified by the user ?
My guess is that it uses 0 C or 273 K, but I would like to reconfirm the same.
Thanks
settler - i haven't had the need to model a physical fluid cavity at any point. but i looked around online and one post had suggested that if it is required to have a fluid then you would probably have to run a co-simulation of abaqus explicit and CFD. i had suggested a box ( ie a closed region)...
hello,
my goal is to perform a static analysis on a 3 cylinder composite by applying an internal pressure on the inner cylinder to begin with. this would be to assemble the cylinders by bringing them in contact.
once this is done i would like to perform a fully coupled temp disp analysis where...
create a box or cylinder that contains your liq. i would use a box as you dont have to deal with cylindrical coordinates. i will leave it to you as how to how design this box based on your problem. create a horizontal partition to separate the liquid nitrogen region from the other region. you...
I would like to know if there is a way to output the heat generation rate (W/m^3) in the Abaqus odb.I have a curved beam to which a non-uniform heat generation is applied.
Qgeneration = f(thickness,length)
I would like to get an output of the applied heat generation to the curved beam just to...
Thought I'll attach a separate plot of COPEN .http://files.engineering.com/getfile.aspx?folder=0ee50de8-88af-4b6e-9586-f77e6a064d23&file=COPEN_plot.jpg
From 0 to 240 degrees I have positive COPEN values(vertical axis on the right has the location of its origin slightly different from that of the primary axis on the left ) and negative contact pressures. The COPEN graph does show negative COPEN values at certain locations in the...
