automobile light weight structural composites are subjected to the various loadings in their service lives. honeycombs are increasingly used as core structures in automobile light weight structures as energy absorbers. in this paper the energy absorption of honeycomb panels under impact of cylindrical projectile is numerically and experimentally studied. the effect of the core materials and cro...

USC’s work on sandwich structure acoustics began in 1998 and has evolved in close collaboration with the M.C. Gill Corporation, a leading manufacturer of sandwich panels for aircraft interiors. The work has had both an applied mission and an academic focus, and presents an example of university-industry collaboration can produce mutual benefit while advancing scientific understanding. Here, we ...

Surface damage on honeycomb aircraft panels is often measured manually, and is therefore subject to variation based on inspection personnel. Eddy current testing (ECT) is sensitive to variations in probe-to-specimen spacing, or lift-off, and is thus promising for high-resolution profiling of surface damage on aluminum panels. Lower frequency testing also allows inspection through the face sheet...

This study analyzes the mechanical behavior of low density polyethylene foam core sandwich panels subjected to edgewise compression. In order to monitor panel response to buckling, strains generated in the facesheets and overall out-of-plane deformations are measured with strain gages and projection moiré, respectively. A finite element (FE) model simulating the experimental test is developed. ...

Due to the need for alternative materials realization of lightweight structures, analysis sandwich structures that have a semi-open thermoplastic honeycomb core as an internal support structure is great technical and scientific interest. Sandwich components with honeycomb-structured layer between two continuous fiber-reinforced face sheets exhibit maximum weight-specific stiffnesses strengths. ...
