Abstract

Thermoplastic honeycombs based on polypropylene are one of the latest types of cores used in SANDWICH STRUCTUREs. Up to now there have been few experimental and MODELING studies on the mechanical behavior of SANDWICH STRUCTUREs with thermoplastic cores. In this paper, by considering the similar properties of foams and THERMOPLASTIC HONEYCOMBs, attempts are made to model the static indentation behavior of honeycombs based on a crushable foam material model using the ABAQUS finite element programme. Comparison of the experimental results and numerical predictions for indentation values show a good correlation up to 20% depth of the panel thickness. It must be noted that in static indentations it would be irrelevant to study the rupture of the skins or cores and, therefore, the crushable foam model should be suitable for MODELING the behavior of THERMOPLASTIC HONEYCOMBs.
