Fast buckling analysis of statically indeterminate variable-section struts

Research output: Contribution to journalArticlepeer-review


The force method, together with the virtual work principle, is used on desktop computers for the buckling analysis of variable-section struts. The method is based on the direct integration of the internal-work integral. The method is applied to struts composed of a thicker midsection and of two thin end sections under axial load. Several different upper-end constraints are considered. Such struts are used in fusion technology and in the cryogenic industry as flexible suports. Analyses appropriate to the flexible support of the toroidal field coils and of the vacuum vessel for the Next European Torus (NET) Project for controlled thermonuclear fusion research are shown as examples.
