1. ABSTRACT X-ray diffraction (XRD) measurements have been made to determine residual stresses in embedded Al particles placed between the first and second ply of both unidirectional and fabric graphite/PMR-15 composite specimens. In order to further verify the results obtained, the effect of externally applied four-point bending on the measured strains and stresses in the Al inclusions was inv...

New spherical codes called laminated spherical codes are constructed in dimensions 2–49 using a technique similar to the construction of laminated lattices. Each spherical code is recursively constructed from existing spherical codes in one lower dimension. Laminated spherical codes outperform the best known spherical codes in the minimum distance sense for many code sizes. The density of a lam...

Ballistic impact mitigation requires the development of protective armor applications from composite material systems with good energy absorption and penetration resistance against threats, e.g., metallic projectiles. In this aim, high-strength high-stiffness soft fibrous materials (such as ultra-high molecular weight polyethylene—UHMWPE) are often used. The high specific strength feature is on...
