Analysis and evaluation of mechanical performance of reinforced sandwich structures: X-CorTM and K-CorTM [PDF]

, 2005
X-CorTM and K-CorTM are foam based lightweight structural cores reinforced with ZFiber ® rods oriented in a truss pattern. They can generate sandwich structures which possess strength- and stiffness-to-weight ratios such to compete with aerospace grade

Modelling of low-energy/low-velocity impact on Nomex honeycomb sandwich structures with metallic skins [PDF]

, 2008
In the aircraft industry, manufacturers have to decide quickly whether an impacted sandwich needs repairing or not. Certain computation tools exist at present but they are very time-consuming and they also fail to perfectly model the physical phenomena ...

Core crush criterion to determine the strength of sandwich composite structures subjected to compression after impact [PDF]

, 2008
In this study a core crush criterion is proposed to determine the residual strength of impacted sandwich structures. The core of the sandwich is made of a Nomex Honeycomb core and the faces are laminated and remain thin.

Mechanical modeling of bending stiffness degradation for soft-honeycomb sandwich structure under CW laser heating

AIP Advances, 2020
Based on the theory of Reissner’s sandwich structure bending, a mechanical model of bending stiffness degradation for a soft-honeycomb sandwich structure under continuous wave (CW) laser heating was established by introducing the equivalent debonding ...
