but how can we know that the load vs deflection curve is correct. With what did they compare this abaqus result to say that, this is perfect geometric nonlinear example. Can anyone answer to my question.
Very interesting and clear video, but I have a question about the load/increment plot at 25:00: Since the load is plotted in Y-direction, isn't the load decreasing after 0.60 because the orientation of the load vector is rotating together with the point to which it is applied? Which of course results in a decrease of force in Y-direction but an increase of force in X- and Z-direction?
Yes. Even I had the same doubt. Since, a load in the y direction is being plotted and as the "follow nodal rotation" check box was checked in the load module the plot does not exactly capture the total force applied at the nodes.
One of the most clear exemples I've found on NonLinear geometry problems. Thx for posting.
Thanks for the comment. Will post more topics soon!
please do so.. this was very helpfull!

Thanx a lot !!! Explanation of the concepts are really very good :-)
Please post more videos
how to define the cable with abaqus
gracias me ayudo mucho

sir please post an example on RC structure subjected to multiple excitations
