| Abstract: |
| In this paper, the large scale nonlinear problem of circular
arch beams under concentrated load is studied by the pseudo arclength algorithm in the finite
element method. The curves of the critical load vs. The center angle and the critical point
between the bifurcation and the simple bifurcation are obtained. The deformations after
buckling are traced. To begin with, the pseudo arclength algorithm is briefly described, then the
calculated results are presented. |
