Summary
Considerable bending and membrane stiffening may occur in the fold zones of discretized models of severly deformed shells. A simplified analysis is presented to illustrate this effect for a single fold and an entire box column subjected to axial compression. It is concluded that the mean crushing force calculated by means of FE methods might be up to 30% larger than the experimentally measured force unless the mesh size is brought down to the dimension of a wall thickness.
