Dear all,
I am working on postbuckling of stiffened composite panels using ANSYS. I have done few experiments and trying to simulate in ANSYS. I have performed nonlinear analysis using arc length method and the load-axial displacement curve obtained is too stiff (having 60% higher slope) compared to the experimental curve. I think BCs, material properties and loading is fine in the model. Can anyone have any suggestions to improve my results?
Will there be any possibility
Will there be any possibility of the fault about the experimental result?
