β¦ Synopsis
In the light of recent contributions by Batozl and Hibbitt: two aspects of finite element formulations for shell stability analysis are examined. The first is the consistency of the shell strain-displacement equations employed; the second is the proper representation of 'follower forces'-pressures that are always normal to the deforming surface. Numerical studies of an arch indicate that improper representation of either of these factors can have a significant effect on predicted buckling loads.

Finite element modelling of processes, where geometry of the component evolves with time, usually involves checks/computations for contact between objects. Examples of these kinds of processes are sheet forming, bulk forming (forging, extrusion, rolling), etc. In some cases, it may be acceptable not
