Apr 17, 2008 Thread starter #4 dkeatley Geotechnical Oct 25, 2007 13 So eigenvalues less than 1 would suggest buckling? Upvote 0 Downvote
Apr 17, 2008 1 #5 MrMyers Mechanical May 27, 2007 70 yes, the alternative is to put a unit load as the applied load and your first eigenvalue is now your buckling load. Upvote 0 Downvote
