nGetting a structure with an applied pressure to show post-buckled results is challenging. Get ready for days (weeks?) of research. One requirement is to introduce some tiny amount of non-uniformity into the model to seed the buckled shape. This can be done by reshaping the geometry with a small amount of the linear elastic buckled shape, or you can apply a small force that will help it to buckle. Here is a YouTube video that explains
can learn something about the critical buckling load and the buckled shape using the linear Eigenvalue Buckling analysis. nStart by taking the Structural Instabilities Course.nhttps://courses.ansys.com/index.php/courses/structural-instabilities/nHere are the discussions on linear Eigenvalue Bucklingnhttps://www.google.com/search?q=site%3Aforum.ansys.com+eigenvalue+buckling&oq=site%3Aforum.ansys.com+eigenvalue+bucklingnHere are the discussions on nonlinear post buckled analysis.nhttps://www.google.com/search?q=site%3Aforum.ansys.com+nonlinear+post+buckling+stabilization+arc-length&oq=site%3Aforum.ansys.com+nonlinear+post+buckling+stabilization+arc-lengthn
