Hello,
I am modeling FRP strands in Prestressed Concrete in ABAQUS. FRP has been defined as orthotropic material whereas concrete as isotropic. The linear analysis results were decent and I was able to relate the results with experiment. however, when i defined the CDP model for concrete (FRP strands were linear only as they are not expected to go in non-linear range during analysis), i am getting stress paterns shown in attached image.
What could be the reason for this?
Any help will be appreciated
