I have modeled a beam prestressed with strands. The model works but I want to plot the bond stress at the interface of strand and concrete versus slip of strand. How I can plot this graph from .odb file?
How did you model the strands and their connection with the beam ? Are they solids with contact between them or did you use e.g. embedded regions constraint ?
I modeled the strands as a 3D circular bar and beam as 3D with hole inside for each strand. I use the surface-to-surface contact interaction using cohesive, normal, tangential, and damage behavior from ABAQUS contact interaction.
