Jul 01, 2008 In this investigation, fixture-based crush initiators were evaluated for producing progressive crushing failures and high levels of energy absorption under dynamic edgewise compression loading. Four different sandwich configurations were investigated, fabricated using woven or random mat carbon/epoxy facesheets with foam or balsa wood cores.
Nov 27, 2014 In this paper, the influence of foam filling of aluminum honeycomb core on its in-plane crushing properties is investigated. An aluminum honeycomb core and a polyurethane foam with densities of 65, 90, and 145 kg/m 3 were used to produce foam filled honeycomb panels, and then experimental quasi-static compression tests were performed. Moreover, finite element model, based …
Feb 12, 2016 On 20 December 2015, a mountain of construction waste collapsed in Shenzhen, north of Hong Kong. The man-made landslide destroyed 33 buildings, killed 69 people, and left 8 others missing ([ 1 ]). This disaster occurred only 4 months after the chemical explosions in a hazardous material storage facility in Tianjin ([ 2 ]). These events highlight the importance of proper design and risk ...

Mar 15, 2020 1. Introduction. The packing characteristics of granular materials have been studied for over a century. It is generally accepted that the comparative density of any granular material is a function of particle shape, size range and size distribution (Burmister, 1938), however predictions for the density or porosity for a granular assembly are usually empirical, and are only semi-analytical at ...

Jul 01, 1997 Composite tubes of different D/t and H/D ratios and made of glass woven mats with epoxy resin, were tested under axial compression. The crushing mode and the energy absorbing capacity of these tubes were studied. Some of the tubes were filled with foam before testing, and the effect of the infill foam on the failure mode and the energy absorbing capacity of the tubes is discussed.
Sep 13, 2018 To provide a theoretical basis for metal honeycombs used for buffering and crashworthy structures, this study investigated the out-of-plane crushing of metal hexagonal honeycombs with various cell specifications. The mathematical models of mean crushing stress and peak crushing stress for metal hexagonal honeycombs were predicted on the basis of simplified super element theory.
