Tripping of stiffened plates using a refined beam theory
Abstract
The subject of this paper is the buckling behavior of thin
bar stiffeners attached to plates which are subjected to normal
pressure loadings. The stiffeners are mathematically modeled by
a nonlinear beam theory recently derived. An analytical solution
is obtained to the beam buckling equations. The curvature of the
centerline along the beam's base at the buckling load is
expressed in terms of the beam's thickness, height, and
rotational stiffness. Analytical results are compared with an experiment recently performed.
