Dear All users for Riks:
It is such a gospel to have Riks as a numerical tool to model structure buckling behaviour.
However, there is a puzzle for me, when I model a column with solid square cross-section under compression. I used displacement control as loading method.
the model can nicely...
Dear mates here:
I got a question if I don't introduce any imperfection to General Riks, and load the same structure with the same load, what is the difference between General Static and General Riks?
From the previous topic, there is an answer from Martin:
Riks is best suited to problems...
Hi all friends:
I am modelling a round bar under axial compression, and want to impose pressure to the body through out the lateral surface, and I want the magnitude of the pressure varies along the axial direction of the bar, I cannot find any suitable way to give this load in the list of load...
Dear friends here:
Thanks for your reply to my previous questions, and I learnt really a lot from this forum, thanks everyone who helped me, May all the things goes well on you!
Now, I found a serious problem when I using buckling in linear perturbation. I know the critical load equals to the...
Dear Forum mates:
I am recently focusing on applying ABAQUS to model the static buckling behaviour of a bar, and sometimes I found the whole or part of the contour shows grey or white color and I was notified that the deformation is not available, what is the reason of that? is that mean some...
Hi all friends here:
I am a new researcher and employ ABAQUS to analyse steel bar buckling through Riks algorithm, and concerning the stopping criteria, I want to ask a question. Since when we edit "step", we can specify as much as three stopping criterion: Maximum load proportionality factor...
