This paper describes a numerical analysis of the buckling of fusion re
actor components, resulting from electromagnetic loads. An analysis me
thod for the calculation of the dynamic electromagnetically coupled bu
ckling is proposed, where the geometrical non-linearity, the magnetic
damping and the magnetic stiffness effects are taken into consideratio
n. In the cases of the analysis of a shallow arch, the numerical resul
ts agreed well with the experimental results. The comparison showed th
at the inclusion of the geometrical non-linearity and the magnetic sti
ffness in the analysis is evidently necessary for good agreement. The
analysis of the ITER vacuum vessel showed that, in the case of plasma
disruption, the possibility of electromagnetic buckling of the ITER ve
ssel is very small under the conceptual design activity condition.
