Abstract
The paper describes FE simulation methods for novel folded structural composite cores being developed for sandwich structures with enhanced performance for use in aircraft fuselage and wing primary structures. To support these materials and structural developments, computational methods were developed in the EU project CELPACT based on micromechanics cell models of the core with multiscale FE modelling techniques for understanding progressive damage and collapse mechanisms. The paper discusses the computational models and applies them to analyse the structural integrity of the advanced cellular core sandwich structures under impact load conditions relevant to aircraft structures.
