Dynamic buckle propagation on Chater's beam

In this paper, a sweeping investigation on dynamic buckle propagation on Chater's beam is performed by using the general nonlinear finite element methods (FEM)instead of any quasi static or dynamic steady propagation assumptions, With the help of the arbitrary Lagragian -Eulerian boundary element method (ALE-BEM) and the weighted residual methodology,the effect of interaction between the beam and the fluid flow inside is also reconsidered based on the two-demensional potentional flow theory.How the structur...
