Impact localization in composite structures of arbitrary cross section

An approximate model for slug flow heat transfer in channels of arbitrary cross section

In this paper, a novel approximate solution to determine the Nusselt number for thermally developed, slug (low-prandtl), laminar, single phase flow in channels of arbitrary cross section is presented. Using the Saint-Venant principle in torsion of beams, it is shown that the thermally developed Nusselt number for low-prandtl flow is only a function of the geometrical parameters of the channel c...

Manufacture of Arbitrary Cross-Section Composite Honeycomb Cores Based on Origami Techniques

As observed in the design of antenna reflectors and rocket bodies, both flat and 3Dshaped honeycomb cores are used in the field of aerospace engineering. This study illustrates a new strategy to fabricate arbitrary cross-section honeycombs with applications of advanced composite materials by using the concept of the kirigami honeycomb, which is made from single flat sheets and has periodical sl...

Impact Resistance of Composite Structures

A new approach based concepts of the Discrete Element Method, is presented for impact resistance analysis of composites. The method is capable of analysing the progressive fracturing and fragmentation behaviour as well as potential post cracking interactions caused by the newly created crack sides and segments. The imminence of a material crack is monitored by an anisotropic Hoffman model . To ...
