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...

A series of analytical and experimental investigations is presented to study the response and failure of pyramidal truss core sandwich panels made of carbon fiber composite under axial compression. In the analytical part of the study, three failure modes: (i) Euler or core shear macro-buckling, (ii) face wrinkling, and (iii) face sheet crushing, were considered and theoretical relationships for...

In this study, we focused on the large inelastic behavior of a sandwich panel made two solid plates as stiffener and honeycomb core shell subjected to blast load. The loading scheme was carried out using an explosive charge bullet mounted at standoff distance 100 mm with three mass variations trinitrotoluene: 1, 2, 3 kg TNT. numerical simulations performed ABAQUS/CAE were validated experimental...
