How to include buckling analysis

[rothchield]

hi all,
im a new user of abaqus6.7. here is my practice: a long thin rectangle plate embeded horizonally into a vertical wall on one end, and the other end is under an impluse force distributed uniformly. but after the explicit analysis, i found the plate just shrinks on the compressing direction, there is not any buckling behavior. my intension is to observe the behavior of the unstable buckling under such force conditions. how do i operate in the abaqus software to let the thin plate buckles not just shrink in one direction?

whilst i know almost nothing about abaqus, what are you looking to see. if the plate, thin though it may be, is loaded in pure compression, then won't it remain the compression instability onset is sudden (like in an euler column) not gradual like in plastic yielding. there would be something different happening if the thin sheet was supported by stiffeners.

You might try posting this question in forum799, as it is aimed at Abaqus users. If you do so, I'd suggest either (1) red-flagging this post or (2) posting a link to your new post.
