Foldcore Structures and their Numerical Homogenisation
Authors: ,
Abstract: The aim of this contribution is to give an overview of the possible applications and mechanical properties of folded sandwich cores. As the name already recognizes the structure is manufactured by folding from a flat semi-finished product. Folded cores possess some properties that make them particularly interesting for the aviation industry. To determine the mechanical properties a numerical homogenisation method has been applied. For a selected type of folded core the properties are exemplarily determined. The procedure is applicable to other types of sandwich cores as well. Also the mechanical properties are similar for other kinds of folded sandwich cores.
