Multi step - Implicit and Explicit

[maajidchishti]

Dear All

I need to model a single lap joint loaded under tension. In this model I have apply a bolt load using Pretension surface and I am using a VUMAT for prediciting composite behaviour. I wanted to know if it is possible to have step 1 as STATIC IMPLICIT and step 2 as DYNAMIC EXPLICIT in a single input file? Please Advice. If this is not possible, what are other ways of doing the same thing.

Your help will be much appreciated.

Thank you

Maajid

It will be possible with version 6.9

No.  See the documentation on transferring results between ABAQUS
analysis (e.g, *IMPORT).

Hello Maajid,
 
At the moment it is not possible to exactly do the way as you requested ("I wanted to know if it is possible to have step 1 as STATIC IMPLICIT and step 2 as DYNAMIC EXPLICIT in a single input file? ")

Abaqus 6.9 has this *IMPORT feature where in the results state of a simulation can be imported on to the next simulation. In your case the result state from the IMPLICIT analysis must be imported on to the EXPLICIT simulation.
 
Another feature that is special to the 6.9 release is the IMPLICIT_EXPLICIT co-simulation which does not serve your purpose.
 
For further info on the *IMPORT functionality, read through the following
 
Transferring results between Abaqus analyses: overview,” Section 9.2.1 of the Abaqus Analysis User's Manual
 
Hope this helps
 
Andy

Hi Everyone,

Thanks for your response. I think *IMPORT is the way to go for me as I dont have Abaqus6.9. Thank you once again.

Regards
