| 摘 要： | Based on the dynamic governing equation of propagating buckle on a beam on a nonlin-ear elastic foundation,this paper deals with an important problem of buckle arrest by combining theFEM with a time integration technique.A new conclusion completely different from that by the quasi-static analysis about the buckle arrestor design is drawn.This shows that the inertia of the beam cannotbe ignored in the analysis under consideration,especially when the buckle propagation is suddenlystopped by the arrestors.
