Strain rate of a simulation in ABAQUS/Explicit? 1

[ShadowWarrior]

I'm simulating a drop impact test. I can find out the strain rate of the physical problem from dividing Velocity by Initial height, but how can I find out the strain rate from the simulation result data?

 

[Mustaine3]

By requesting the strain rate as output and looking at it.

 

[ShadowWarrior]

Can you please name the output variables for strain rate?

 

[Mustaine3]

That information is easy to find in the Users Manual.

From version 6.14-1, Abaqus has introduced Equivalent plastic strain rate (PEEQR). Link -

But I cant find the PEEQR output variable in either Field or History output dialogue box.

Any help?

Did you select an element or an element set in the field/history output dialog box?

Yes, I have selected an element set, but its still not showing up.

ER = Total strain rate (available)
PEEQR = Equivalent plastic strain rate (Not available)

If it is not supported in /CAE, then you can add it in the Keyword-Editor or write out the .inp and add it there.

I have included the PEEQR keyword in .inp file, there was no error, everything ran fine.

But still no PEEQR output variable in .odb file.

 

[ShadowWarrior]

For future reference -

PEEQR keyword is not supported in ABAQUS/CAE 6.14-1, but it is supported when manually editing the .inp file, only for *Rate dependent material models.

It will not be available in the .odb file if the rate dependent keyword is not present in the .inp file.

Thanks to Mustaine3 for the tip.
