How to get forces from stresses in abaqus 1

[raghabk]

Hello everyone

I have modelled an I-girder in abaqus using shell elements.
Can anyone tell me how to get forces from the stresses. I
modelled 3D but output stresses are plane stresses.

any response is much appreciated

1) surely Abaqus proves output in forces ? mind you it'll be forces and moments.

2) else stress*area = force ??

3) why do you want forces ??

Dear rb1957

I could not find how to get forces from Abaqus when modelling in shell
elements. All the guides and online searching talk about how to get them
for beam elements. I apologise I did not clarify properly, I would like to find
forces from plane stresses i.e if I have mises stresses and all the stresses that I
can find out through abaqus. Can I calculate the force by just using the mises
stresses criteria to find an equivalent stress and then using that stress
to multiply by area?.

Thank you for your help

sorry didn't answer properly to question 3
I am currently studying the postbuckling phase
of shear panels in plate girders and the subsequent
axial force they generate on transverse stiffeners.
So I would like to compare the force generated in my model
to different design models

Surely Abaqus calculates the nodal forces ? (I really think so)
maybe your post-processor doesn't give you the option to plot them ? (don't think so, it should plot all the output vectors)
maybe you didn't ask Abaqus to include them in the output ? (probably where you should look)
maybe you need to look at the Abaqus output file to see them ?? (that'd be too olde school)

Dear rb1957

Thank you for the help, I found a few tricks that can help me do this
I have to request it from Abaqus. Again thank you for the help, exhaustion
has a way of turning me into an idiot.

thank you very much
