Title:	Wandelbare Faltungen aus biegesteifen Faltelementen
Abstract:	Wandelbare Faltungen vereinen die statischen Vorzüge zueinander aufgefalteter Flächen mit denen der Veränderbarkeit der ganzen Struktur. Voraussetzung für die statische Nutzbarkeit ist die Tragfähigkeit und damit die Biegesteifigkeit der Faltflächen, die wiederum Faltelemente aus entsprechend biegefestem Material von endlicher Dicke bedingen. Infolgedessen muss die Beweglichkeit der Faltflächen zueinander ausschließlich über die gelenkigen Zwischenverbindungen erzeugt werden, deren notwendigen Bewegungsfreiheitsgrade sich in Abhängigkeit von der Art und Konfiguration der Faltung und der Abmessung der Faltelemente bestimmen. In den folgenden Ausführungen werden die wichtigsten Aspekte dieser für wandelbare Faltungen typischen, wechselseitigen Abhängigkeit von Kinetik, Statik, Faltstruktur und Konstruktion beschrieben. Deployable folding patterns using stiff plate elements. Deployable folding patterns unify the structural advances of folded plate systems with the deployability of the whole structure. The essential requirement for the structural usability is the load bearing capacity of the plate elements and therefore its bending stiffness resulting in bending resistant materials of finite thickness. Therefore only the flexible connection between the plate elements must induce the movability. The degree of freedom of the connections is determined by the matter and configuration of the folding pattern and the dimensions of the folding elements. In the following the most important aspects of typical interrelated dependencies within kinetics, structure, folding systems and construction regarding deployable folding patterns will be described.
