    Abaqus contact/constraint problems

    I have applied constraint to the curved plate and the simulation works. However, I'm getting multiple warnings: 1) "Displacement increment for contact is too big" - 2) "There is zero FORCE everywhere in the model based on the default criterion". When running animation, the top plate forces the...

    Abaqus contact/constraint problems

    So I have tried using the general contact and also surface-to-surface contact with friction, but both of them aren't working. I am getting negative few eigenvalues for some reason. Any advice please?

    Abaqus contact/constraint problems

    Hi, I have a curved deformable plate that I wish to flatten using 2x flat plates (1 at the top and 1 at the bottom). My question is, do I choose those 2x flat plates as a discrete or analytical rigid model? In terms of the contact property, I imagine it will be a surface-to-surface contact with...

    Capturing curvature/radius on Abaqus

    Just to add, how can one get the "3D mesh to geometry" plugin? I'm using the 2023 Abaqus ver. I have also tried using the Face -> From element faces, but it does not seem to work properly...?

    Capturing curvature/radius on Abaqus

    Very good point indeed @FEA :) I did not think of that. I will try both methods and see which one fits better. Thanks

    Capturing curvature/radius on Abaqus

    Cheers for the reply! Just to be clear, would it be something like this?

    Capturing curvature/radius on Abaqus

    Hi, I have got a square plate that's deformed due to thermal stress. How can I extract/calculate the curvature or radius of this deformed plate? Cheers

    Warped composite plate

    Hi, I'm quite new to Abaqus. I have modelled this composite flat plate that has deformed due to temperature change. I want to perform a compression test on this deformed plate to flatten it again, so that I can see the energy required to do so. Any advice on how I can do this please?
