Identification of honeycomb sandwich properties by high-resolution modal analysis
A method is proposed to identify the mechanical properties of the skin and core materials of honeycomb sandwich. All the elastic coefficients and loss-factors that matter in the dynamics of a panel in the thick-plate approximation are identified. To this end, experimental natural modes (i.e. eigenmodes of the damped system) are compared to the numerical modes of a large sandwich panel (lx,y/h ≃...
متن کاملLoss factors of honeycomb sandwich structures: an experimental approach
Loss factor measurements were performed on different sandwich panels to determine the effects of different skin and core materials on the acoustical properties of sandwich structures. The study included the following panel/beam designs: glass-epoxy skin with a meta-aramid (m-aramid) core, glass-epoxy skin with a para-aramid core, carbon skin with a m-aramid core, carbon skin with a m-aramid cor...

متن کاملQuasi-static Punch Indentation of a Honeycomb Sandwich Plate: Experiments and Modelling
Punching experiments on wide honeycomb sandwich beams were performed to evaluate the predictive capabilities of a newly developed constitutive model in structural applications. The employed constitutive model for plastically com-pressible orthotropic materials accounts for both non-uniform hardening and softening associated with stressing in different directions. This feature is vital when asse...
متن کاملA Theoretical and Experimental Study of Failure Maps of Sandwich Beams with Composite Skins and Honeycomb Core
Failure maps of sandwich panels such as beam, plate and shell are of great importance in designing such structures. In this paper, failure maps of sandwich beams with composite skin and honeycomb core are obtained. The effect of transverse shear in skins and core and the effect of double walls of honeycomb core have been taken into account. Shear deformation of skins and core are assumed to be ...
