Dear friends and researchers
I've modeled a RC tunnel segment in Abaqus.
1- In order to define plastic behavior of Concrete, I used CDP model and Hognestad relation to achieve a complete stree-strain curve of concrete( in Tabular format).
2- I've just used "Embedded region" Constraint to embed rebars into Concrete.
3- There is just one axial load (TBM thrust Jack) which is applied on the circumferential seam of the segment.
4- I used T3D8 elements for Rebars(Truss section for rebars) and C3D8R elements for concrete(solid section).
But in the end of these steps; after I ran the model, I didn't got any useful result.
I want to know and identify those areas which is in plastic behavior.
When I request to show plastic strain(PE) as a field output. there is no useful result and plot(In history output).
here I brought my model figure and Hognestad relation.
It's so helpful If you can help me.
Thanks.
Have you tried to get the PE values for the other statues rather than "Max in plane"?
