G. Salerno et R. Casciaro, MODE JUMPING AND ATTRACTIVE PATHS IN MULTIMODE ELASTIC BUCKLING, International journal for numerical methods in engineering, 40(5), 1997, pp. 833-861
This paper summarizes a part of the first author's Ph.D. Thesis(1) com
pletely devoted to multimode elastic buckling within an FEM strategy.
The theoretical arguments unfold among critical points on radial paths
(the unique post-critical paths variationally defined), algebraic cha
racterizations, proposition demonstrations and so on, by aiming to pro
ve that the complexity of the phenomenon of multimode buckling (second
ary bifurcations, post-critical attractive paths) can be theoretically
explained.
