Hello Everyone !
I try to validate FEM pullout test of single bar by comparing results with test data.
I have performed laboratory pullout test, as a result getting test curve - relation.Force - Displacement
I know internal friction angle of filling material and value of external pressure - in my opinion - this is
everything to compare results with predictions in PLAXIS 3D.
In Plaxis i have done a few models with different Rinter value.
I expected that some of FEM curves will be close to experimental ones
Unfortunately - the slopes of the FEM curves are the opposite that in experiment.
What could be the reason?
Regards!
Andrzej
