Post-buckling response

In order to examine the phenomenon of film buckling and possible subsequent delamination, this section begins with a description of the simplest case of buckling under plane strain conditions. This is followed, in subsequent sections, by analysis of circular buckles, secondary buckling phenomena and buckles with perimeters of other shapes. [Pg.343]

If these features are incorporated into the model, the strain-displacement relations take the form [Pg.345]

Even though the deformation is in the geometrically nonlinear range, the differential equation governing w x) is linear. This is a fortuitous outcome that follows naturally from the nonlinear von Karman plate theory. A solution of (5.5) is sought subject to the boundary conditions [Pg.346]

The differential equation in (5.5) and the boundary conditions (5.6) have the form of an eigenvalue problem for a one-dimensional continuous system where the variable ta represents the eigenvalue. The eigenvalue of least magnitude for which a nontrivial solution exists is [Pg.347]

No positive eigenvalues exist in this case. The compressive force in the film cannot be increased by buckle formation, so that At = — tin 0. The [Pg.347]

Fig. 5.10. Normalized transverse deflection along the axis of symmetry following buckling versus the normalized value of excess compressive stress in the film. The figure shows the asymptotic prediction of post-buckling response (dashed line) and finite element simulation (solid line) for hf/a = 0.05 nd i/f = 0.25. Fig. 5.10.

Typical load-lateral deformation responses at midheight are shown in Figure 7.33 for temperatures up to 180 °C [22], At 220 °C, deformations were less than 0.5 mm and therefore below the photographic measurement accuracy. The curves exhibit similar pre- and post-buckling shapes and temperature-dependence as shown in Figure 7.32 for the axial displacements. [Pg.170]
