Development of a SMA hybrid composite jet engine chevron concept

SPIE Proceedings, 2007
Control of jet noise continues to be an important research topic. Exhaust-nozzle chevrons have been shown to reduce jet noise, but parametric effects are not well understood. Additionally, thrust loss due to chevrons at cruise suggests significant benefit from active chevrons.

Thermal post buckling analysis of smart SMA hybrid sandwich composite plate

Polymers and Polymer Composites, 2021
Thermal post-buckling analysis of smart sandwich plates has been presented with the incorporation of shape memory alloy (SMA) and shape memory polymer (SMP) in laminated composite structure under uniform temperature distribution. Buckling analysis is based on higher order shear deformation theory (HSDT) with von Karman nonlinearity by finite element ...

Virtual processing of hybrid SMA composites through martensitic transformation

SPIE Proceedings, 2011
The capability of Shape Memory Alloys (SMAs) to modify the reference configuration of an SMA-composite through martensitic transformation is explored. It is intended that through careful selection of a thermomechanical loading path the composite can be "processed" such that the constituent phases are in a preferential reference configuration ...

Investigation on the Mechanical Properties of SMA/GF/Epoxy Hybrid Composite Laminates: Flexural, Impact, and Interfacial Shear Performance

Materials, 2018
In this article, hybrid composite laminates with shape memory alloy (SMA) and glass fiber (GF) as the reinforced phase, and epoxy resin as the host material, were manufactured by vacuum-assisted resin injection (VARI) processing.

Pseudo-elastic hysteresis damping characteristics of SMA hybrid composite lamina

Journal of Wuhan University of Technology-Mater. Sci. Ed., 2008
The longitudinal mechanical behavior of shape memory alloy (SMA) composite lamina subjected to longitudinally strain or stress controlled cyclic loading is investigated. The SMA is under pseudo- elastic condition and the fibers are embedded (bonded) to the host material.

Coupled Deflection Analysis of SMA Fiber Hybrid Composite Active Blade

Advanced Materials Research, 2009
The constitutive equations relating cross-sectional loads(forces and moments)to cross-sectional displacements(stretching, bending, twisting) of thin-walled laminated beams with integral shape memory alloy (SMA)active fibers was presented. The variational asymptotic method was used to formulate the force- deformation relationships equations, accounting ...

Numerical Prediction of Effective Transformation Properties of Hybrid SMA-Ceramic Composites

ASME 2010 Conference on Smart Materials, Adaptive Structures and Intelligent Systems, Volume 2, 2010
Metal-ceramic composites are being increasingly explored in an effort to find new materials for use in extreme environments. Via functional grading of of the volume fraction of the constituant phases and other techniques, the material can be optimized to incorporate the mechanical properties of the metal phase with the thermal properties of the ceramic

Optimal design of damping layers in SMA/GFRP laminated hybrid composites

Smart Materials and Structures, 2017
Abstract This work describes the optimization of the shape profiles for shape memory alloys (SMA) sheets in hybrid layered composite structures, i.e. slender beams or thinner plates, designed for the passive attenuation of flexural vibrations.
