.Lck file issue and Prestressing of CFRP strands in beams in ABAQUS 1

[Zain_117]

Hello Everyone,
1. I am trying to model a beam pre-stressd with CFRP strands. Initially, the software works well, but now all the time it takes much time and .lck fie generated. I am unable to see any .odb file for results. How can I see my result?
2. I want to apply prestress in CFRP tendons but as I am beginner, how I can it be possible? I just want to see the effect of release/detention of these pre-stressing tendons on the cross-section of beams such as cracks and concrete strain.
Can anyone help me to solve the above two problems 1 and 2. The model CAE file is attached.

You misunderstood the idea of an embedded region. It should be used only when a part is placed inside another part, without a cut in the larger part for the smaller one. In your case, there's a cut so you should remove it or use tie constraint instead of embedded region to connect those parts.

Prestress can be applied using initial conditions. Check the documentation chapter Prescribed Conditions --> Initial Condition Types --> Defining Initial Stresses.

Few way, thank you for the information. I will check that. By chance, have you look into my model? Also, .Lck file problem is still there and any suggestions to run my model in my software?
Stay connected.

Yes, I checked your file and there was only an error message related to incorrect usage of the embedded region.

Thank you FEA way. What about the pre-stressing action? I hope you have checked that also.
