A Wider View

This Chapter discusses a few special aspects related to numerical investigations of structural stability. While the problem settings can be very diverse, dependent on problem class and objective of investigation, a sound understanding of the stability phenomena can guide numerical analyses. While the most basic aspects of structural and forcing modeling are covered in the previous Chapters, three important general aspects are considered here. These are emphasized by illustrative small examples, where the structural modeling through finite elements is straight-forward, but some aspects in the response need special care. The reported examples are verified to show the same types of behaviour also for very finely discretized models.
