Hello All,
Please, What would be a good procedure to get the maximum loads (or contact pressure ) to avoid a local buckling in a pipe, for example : a straight pipe supported on the middle of span ( the region pipe/support ) and the maximum moment which could be applied on a curved pipe (elbow)...
Hello all,
Could be possible to simulate with Abaqus a local buckling on a thin pipe, for example: a straight pipe supported in the middle of span or to get the maximum moment to avoid the local buckling on curved pipe ?
Thanks
Hello John Breen,
Thanks for your traditional attention!
If possible, I would like to continue a quite more this discussion and I really would apreciate your comments.
1) I did a plastic simulation with Abaqus FEA (including cyclic hardening) using a small pipe ( 11/2" sch40)...
Hello everyone !
I have studied the codes Asme B31.1 e B31.3 and I still did not find some answers for these questions which I would like to receive your comments and opinions:
a) The self-springing effect from A.R.C. Markl paper, which introduced the displacement allowable stress SA, it had...
Hello All,
I would like make a Creep simulation to a steel pipe using Abaqus 6.5 and I am having some doubts about the parameters to input on properties.
The power law that I know is: relative strain(time) = beta*Sigma^n and for my case I have the following parameters:
Relative strain (time )...

Hell all,
I am doing a thermal stress analyse (due to expansion ) in a pipe and the initial boundary condition to the ends of pipe would be encastre ( 06 dof lockeds )but I would need to release the radial expansion only in the ends keeping the encastre ( like a gap or "floating encastre" )this...
Hello All,
I need make a simulation which I have a pipe under thermal loading and your boundary ( end of pipe )is connected to a device (flange) which has a radial displacement to temperature expansion, too
Initially my pipe need a boundary constrain with 06 dof equal to zero but the radial...
Hi all,
I started recently to work with Abaqus using thermal cicling loading and plasticity. To a first model ( a carbon steel pipe ) I used several steps increasing and decreasing the temperature values ( temp. room up to temp. max. and return to room ) and initially I think that were...
Hello everyone,
Some weeks ago I started a discussion about the rules presented in ASME code to flexibility analysis, in special about the allowable stress SA ( due to thermal displacements )which were got from Markl paper.
I have studied some models (with Abaqus - FEA) with nonlinear...
Hello, All !
I am a new user with Abaqus 6.5 and would like to develop a model to verify the level of stresses before and after a ciclic loading ( with temperature and pressure on a pipe ). One case the level of loading will reach the yeld point ( local plastic strains ) and the second case...
Hi ?
I would like to start to work with Abaqus 6.5 but I am not getting to find tutorials or examples using tools- box/windows, etc. only statement lists. How could I get this material ?
Thanks
Hello everyone, In spite of to use the rules presented in ASME code to flexibility analysis, recently I solved to study the origins and concepts about allowable stress SA and I found the paper wrote by A.R.C. Markl (1956 )which was applied by ASME to piping-flexibility analysis.
The stress...
