Experimental Characterization and Numerical Modelling of the Non-Linear Mechanical Behaviour of Nomex Honeycomb Core

Résumé

In this paper, a constitutive model dedicated to the non-linear mechanical behaviour up to failure of Nomex honeycomb cores is proposed. In nautical applications such as multihull sailing race boats,sandwich structures made of carbon/epoxy skins and Nomex honeycomb core are widely used. In terms of service, these boats have to face numerous severe mechanical loadings: wave impacts, slammings and violent swellings of veil, loadings which can lead to local failures of sandwich panels and eventually to abondons. As a consequence, the use of suitable constitutive laws appears necessary to ensure a safe design of these structures.
