Simulation of the dynamic buckling process of cylindrical shells by the finite element method

摘要

In this paper, the buckling process of elastic cylindrical shells has been simulated by carrying out nonlinear dynamic analyse using the finite element method. The computational procedures used during the simulation is first explained. This is then followed by a description of stability criteria for instantaneous state of motion. The capability of nonlinear dynamic analysis in tracing the process of buckling is shown using the example of buckle propagation in a long shallow cylindrical panel. From the results obtained, it can be concluded that buckling process observable in the experiment could be realistically simulated.
