Hi all,
I modelled a beam subjected to fire, I applied all the elements temperatures input to my model as the experiment results. The fire test last 40 mins, I have the beam temperatures recorded every 1 minute in the test.
In the FE model, I used *AMPLITUDE to define the total time step of 10...
Hi, I have an I-section built with shell elements, the cross section is at the X-Y plane, then the span is along Z direction, as shown in the attached image file. Loads applied on the top flange. I want to see the stresses generates on the WEB, which stresses output should I refer to? S11 or...
Thanks bassmanjax,
I got the eigenvalue from *buckle, I carry on with the load-displacement analysis, by using *Static, *Dsload. I apply *Imperfection on the model, but nothing happen.
The results (displacement) with and without the *imperfection are the same. Part of my input file as follow...
what material is that?
for steel, *plastic will do the compression and tension strength of the material.
for concrete, u have to define compression and tension seperately. i.e *concrete damaged plasticity, *tension softhening.
hope this help.
Thanks bass,
so I can choose any scala factor (10%, 15%, 20%)? But how do I know what scala factor value is the one i am 'looking for'?
If I have negative eigenvalues, should I ignored them, and 'call' only the positive eigenvalues from the *buckle analysis to *imperfection?
please advise.
Hi xaktsaroth,
Thanks for reply.
I am modelling a composite structure (I beam + concrete slab), i used brick elements for slab and shell elements for I beam, wondering how to 'tie' both components together (as the 'tie' function in abaqus) so that both components could act as single composite...
Hi,
The analysis of my file was completed, i had 2 steps in the file, 1st step is apply loading (say 100kN), 2nd step is apply heat (say 500 degree celcius). I had my restart file writen.
i am happy with my 1st step result, but not very satisfy with the 2nd step result.
wondering would that...
Hi,
I model a slab, in my model consisted of 2 step:
step 1= apply load
step 2= apply heat (temperature) with constant load.
anyone got any idea why i not getting my external work energy (ALLWK) = internal energy (ALLIE)?
My understanding that ETOTAL=0.0 (ETOTAL=ALLIE-ALLWK), but the results...
yes,
you have to use composite section in shell, divide the shell thickness (say 100mm) into parts (say 5 parts), hence u will have 5 x 20mm thick of shell, u could apply amplitude to the shell with different temperature.

Hi all,
would that be possible to put temperature into every layers of the solid composite layup?
I have a 130mm thick slab, built up with solid elements, I divided the thickness into 10 layers (13mm per layers), i would like to apply different temperature to every layers of the slab, i.e 20oC...
Hi all,
can I continue an abaqus job that accidently been disrupted? I was running an analysis, my PC shut down suddenly while the file still running. I tried to open the unfinished *.odb file, it gave error...

Hi all,
wondering would that be possible to shift 2 different type of elements in a model.
i.e i use SHELL element S4R in my 1st step, after completed the 1st step analysis, I would like to use DS4 SHELL element (on the same set of elements) to carry on the 2nd step.
the reason that i want to...
