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...
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
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...
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...
Hi,
I have a working model of 3 concentric cylinders with the cylinder in the middle being the master surface and the other two being the slave surfaces. I have a pic attached of the model , which would better represent my question.
A gap opens up between the middle cylinder and the outer...
I'm trying to analyze the thermal stresses induced in a pair of concentric cylinders due to a radially outward heat flux. I model them as being in perfect contact and there is a unifom heat flux load that is applied to the inner surface of the inner cylinder and the heat flow is radially...
In a sequentially coupled thermal stress analysis , once the thermal part is complete , should the temperatures be fed into the structural analysis using a predefined field in the ' Initial Step ' ? I just wish to clarify .
thanks
Could anyone shed some light on the correct method to obtain the radial stress values once the coordinate transformation has been performed from rectangular to cylindrical coordinate system.
I have got 2 cylinders in contact and I'm interested in obtaining the radial stress as a function of...
I'd like to know how to extract the radial stresses once a cylindrical coordinate system has been created .
Do S11,S22,S33 correspond to the stresses in the R,THETA and Z directions respectively ?
Hi,
I’m performing a fully coupled thermal stress analysis of a foil sandwiched between 2 cylindrical tubes.
Kindly look at the attached file to see how the foil is oriented between the cylinders.
Also , I have the message filed and cae file attached.
The 2 ends of the cylindrical tubes are...
Hi , i'm conducting an analysis on a flat plat that is simply supported along the length on both sides and free at the other ends.
Kindly view the attached image to view the coordinates.
I implemented these boundary conditions along the
left side of the plate :

Hi ,
I would like to know where I can find a heat transfer and thermal stress analysis tutorial. I would like to go over this before I begin my actual analysis.
Thanks
Hi , I have my problem described along with a figure (see attached) .
I was told to assume a linear profile for the pressure distribution and based on the values of pressure at the trailing edge ( 0 pa) and leading edge(1000 pa) , I obtained an expression for the pressure distribution ...
