Buckling Analysis in Plate

Please login with a confirmed email address before reporting spam

Hi, I want to find the critical load of a plate with simply supported boundary conditions. And compare with analytical results. But I did not get the correct value. You can see further detail in the screenshot(Buckling_Plate_SSSS.png). The comsol file is also attached. Kindly tell me how I can fix this error.

Best, Rauf

Plot the stresses (for example principal stress vectors) from the preload case to check your boundary conditions. You will, most certainly, spot the problem there.
