@Jasosri: please shorten the title of the issue and put the actual request in the main text.
Hey, the buckling solver is rather new in Kratos. You can have a look here #5938. What kind of buckling analysis would you like to perform? Linear/Nonlinear? The solver that is implemented so far can handle both, but covers only the prebuckling phase. We usually use GiD as preprocessor to generate the input files and mesh data. However, the buckling analysis is not incorporated into the GiD interface, yet. Nevertheless, you can just export a standard FEM analysis and adjust the ProjectParameters.json file afterwards manually. Here is an example of a nonlinear buckling analysis of a simple beam/column under compression. BeamBuckling.zip
Be also aware, in the MainKratos.py you need to call the StructuralMechanicsPrebucklingAnalysis
and not the StructuralMechanicsAnalysis
.
Thank you very much @manuelmessmer , I want to perform linear buckling analysis for composite plate.
I just noticed that the number of loadsteps in the ProjectParameter.json is set to nstep=0 in the example I sent you. Just set nsteps = 20 for a nonlinear analysis and nsteps = 2 for a linear analysis. Btw, the time parameter t is utilized as the load multiplier. So the TIME that is printed in every iteration equals the currently applied load multiplier.
Thank you @manuelmessmer for the information.
Hi, I'm new to Kratos, I want to use Kratos for buckling analysis of composite plate. Could you please explain how to create the input file for Kratos?
