Elastocaloric cooling has been identified as a promising alternative to high global warming potential vapor compression cooling. Two key bottlenecks adoption are the need for bulky/expensive actuators provide sufficient uniaxial stress and inadequate elastocaloric material fatigue life. This paper defines physics that govern performance of axisymmetric flexural bending use an emerging low-force...

To simulate the forming process of a unidirectional (UD) glass fiber non-crimp fabric (NCF) for wind turbine blades, material needs to be characterized. In this way, input model simulation can generated. One important deformation characterize is out-of-plane bending. A number test setups have been described in literature but it not clear which setup more appropriate UD NCF under consideration. ...

This article presents a design method of Longitudinal-Bending Coupled Horn (L-BCH) giant magnetostrictive transducer utilized in spinning ultrasonic machining. The structural parameters are initially determined by the theory horn and thick disc. Then, effect rotating wheel on vibration characteristics L-BCH explored model harmonic response analysis through finite element method. Through continu...

In this study we analyzed both bending and impact stress of the discharge valve of the rotary compressor using a commercial FEM program MSC/NASTRAN and predicted the amount of maximum stress and the location it occurred. We measured the maximum stress of the valve in bolt case compressor using the resistance type strain gages. Good agreement was made by the comparison between the numerical anal...

The inherent stability of two-dimensional motion when hovering using beating wings that have a passive feathering is compared with rotary flapping motion. the determined by bending elasticity, which expressed spring at wing root. torsional damper and values were minimizing necessary power in present analysis. Unlike motion, do not pitch/roll damping. A flying robot requires quicker flight contr...

Initiative: The Tygerberg Children's Hospital and Rotary Telemedicine Project in South Africa links specialists from Tygerberg Hospital to doctors at regional community or "district" hospitals to improve healthcare in rural areas. The initiative has assembled its own telemedicine system using off-the-shelf computer equipment and software that is more affordable than commercial telemedicine syst...

An analytical and numerical solution for the free vibration of laminated polymeric composite plates with different layups is studied in this paper. The governing equations of the laminated composite plates are derived from the classical laminated plate theory (CLPT) and the first-order shear deformation plate theory (FSDT). General layups are evaluated by the assumption of cross-ply and angle-p...
