瓦楞纸板对大气条件非常敏感。这项工作的目的是研究这些参数的影响，事实上，相对湿度（RH），瓦楞纸板类型的夹层结构的力学行为。为此，在各种相对湿度下进行拉伸试验。在高湿度下，必须调整仪器。对几种力学性能测试方法进行了初步比较。它可以使用位移测量来验证应变测量方法，这需要对样品进行最小的处理。在这项研究中，水含量对力学性能的影响。此外，这种材料的粘弹性特性与损伤耦合是突出的。(C)2007爱思唯尔有限公司保留所有权利。
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 behaviour of a sandwich structure of the corrugated cardboard type. For that, tensile tests were used under various rates of relative humidity. In high rates of moisture, the instrumentation must be adapted. A preliminary comparison of several measurement methods of the mechanical properties was carried out. It made it possible to validate the method of strain measurement using the measurement of the displacement which requires a minimal handling of the specimen. During this study, the effect of the water content on the mechanical properties is presented. Moreover, the viscoelastic character coupled with the damage of this material is high lighted.
