Question on modelling cement sheath integrity in Abaqus

[Arash Nasiri]

dear all
-Can Abaqus model the cement integrity during the curing (I need to understand how the stresses are changing and what type of forces are excreting on the casing during the curing)
-What properties should be assigned to the interface (between casing and cement/ and between the formation and cementing)
tnx

 

[FEA way]

Yes, it should be possible to simulate this using CDP material model and surface-based cohesive behavior for interfaces.

Check the article "Evaluation of cement sheath integrity subject to enhanced pressure" by E. Arjomand et al.

Dear all
I have a question regarding the mesh geometry in ABAQUS.
Can Abaqus open a prepared mesh geometry (if so which formats? e.g. STL) or this should be defined inside Abaqus itself?
thanks.

Yes, you can import mesh created in external software. That’s so called orphan mesh (without underlying geometry). You can also import STL files using built-in plugin.
