STUDY OF THE HYGRO-MECHANICAL BEHAVIOR OF CORRUGATED CARDBOARD
Résumé
Corrugated cardboard is very sensitive to atmospheric conditions. The aim of this work is to study the effects of these parameters, in fact the relative humidity (RH), on the mechanical behavior of corrugated cardboard sandwich structure. Tensile and three-point bending tests were used under various rates of relative humidity. An analytical model based on the classical laminate plate theory is used to predict the elastic behavior of the corrugated cardboard under different atmosphere conditions. After that the model is used to predict the inelastic behavior of the material from that of its components.
