Reply To: Difference in force-deflection curve (Remote displacement vs Loading Plate)

Hi

See if this tutorial (link below) helps. So just use a displacement with y non zero and x and z free on an edge – so do not use a remote displacement with all zero except of y of course. The tutorial also shows how to extract the failure load (force reaction of imposed displacement).

As for why you get different values, could be many things (material properties etc.) . In theory it could be able to capture the failure of a RC beam.

Some test cases where it has been used: https://www.researchgate.net/publication/354765497_Calibration_and_Validation_of_the_Menetrey-Willam_Constitutive_Model_for_Concrete.

All the best
