Journal ArticleDOI
A constitutive model for shape memory alloys considering tensile¿compressive asymmetry and plasticity
TL;DR: In this paper, a constitutive model for shape memory alloys is proposed, which considers both tensile-compressive asymmetry and plastic strains that occur in the thermomechanical behavior of SMAs.
Journal ArticleDOI
Floquet waves in anisotropic periodically layered composites
TL;DR: In this paper, the dispersion spectrum of a cross-ply periodic laminated is described by a combination of six partial waves (Floquet waves) and a closed-form algebraic solution is derived.
Journal ArticleDOI
In-fiber Fabry-Perot interferometer for strain and magnetic field sensing.

TL;DR: Sensors using an in-fiber Fabry-Perot interferometer used in strain and magnetic field (or force) sensing were found to be over 4 times more sensitive to magnetic fields and around 10 times less sensitive to temperature when compared to sensors constructed with Fiber Bragg Grating.
Journal ArticleDOI
Chaos in a shape memory two-bar truss
TL;DR: In this article, the structural response of a shape memory two-bar truss is studied and a polynomial constitutive model is used to describe the behavior of the shape memory bars.
Journal ArticleDOI

TL;DR: The proposed all-optical fiber sensor is able to detect NS1 antigen at different concentrations, with limit of quantification estimated to be 0.074 μg/ml = 1.54 nM, indicating that the sensor could potentially be used for dengue diagnosis in the acute phase of the infection.
