Geometric Buckling
The geometric buckling is an eigenvalue problem that can be solved for different geometries. The table below lists the geometric buckling for some common geometries.
| Geometry | Geometric Buckling Bg2 |
|---|---|
| Sphere of radius R | |
| Cylinder of height H and radius R | |
| Parallelepiped with side lengths a, b and c |
Since the diffusion theory calculations overpredict the critical dimensions, an extrapolation distance δ must be subtracted to obtain an estimate of actual values. The buckling could also be calculated using actual dimensions and extrapolated distances using the following table.

Famous quotes containing the word geometric:
“New York ... is a city of geometric heights, a petrified desert of grids and lattices, an inferno of greenish abstraction under a flat sky, a real Metropolis from which man is absent by his very accumulation.”
—Roland Barthes (1915–1980)
