| Abstract: | For exact estimation of efficiency of a buckle arrester, it is necessary to take the effect of structural inertia into account in the analysis of buckle propagation on elastic structures after meeting arresters. Under this consideration, this paper deals with the dynamics of buckle arrest and its numerical simulation on the basis of the beam system model used by Chater and Hutchinson (1983). The FEM combined with an improving arc-length control method is adopted to solve the dynamic equations describing the arresting of buckle propagation. A new group of parameters for arrester design which differs greatly from that by the quasi-static analysis is obtained. The present results support the conclusion that the inertia of the beam cannot be neglected in such analysis. |
