Simple Model for SMA Hybrid Composites and Application to Damping Property Analyses.

Journal of the Japan Society for Composite Materials, 1997
Analytical predictions of the constitutive relations and the damping capacity of TiNi shape memory alloy (SMA) fiber embedded hybrid composite lamina have been presented. The stress induced martensitic (M-phase) and rhombohedral (R-phase) transformations of the TiNi SMA fiber are taken into account in the macro-mechanical constitutive modeling of SMA ...

Macroscopic Mechanical Characterization of SMAs Fiber-Reinforced Hybrid Composite Under Uniaxial Loading [PDF]

Journal of Materials Engineering and Performance, 2013
This paper presents an experimental and theoretical investigation on the macroscopic mechanical behavior of shape memory alloys (SMAs) fiber-reinforced glass/resin composite subject to uniaxial loading at ambient temperature. A series of unidirectional SMAs reinforced composite laminates is fabricated through vacuum-assisted resin injection.

Structural Colors from Modulated Topological Defects in Molecular Smectic Liquid Crystals

Advanced Science, EarlyView.
Rather than using dyes and pigments, nature produces the colors of some butterflies and beetles through optical interference phenomena. This study describes an original biomimetic strategy exploiting the spontaneous formation of modulated linear defects in thin films of 8CB, a common molecular liquid crystal.
