Abstract
The manufacturing of shaped sandwich components is a task with technical challenge. In this paper the mechanical feasibility to produce a doubly curved panel from an initially flat sandwich plate was investigated. Experimental results of multi-point forming (MPF) and finite element analyses reveal that the formability of sandwich panel with egg-box-like (EBL) cores in plastic forming process is mainly dominated by the failure modes of face sheet...
