Bending effects on Nb 3 Sn wires have been investigated to understand the critical current degradation of large Nb 3 Sn superconducting cables, such as the ITER conductors. Characterizations of the critical currents of various Nb 3 Sn wires were carried out by a previously reported pure-bending strand test device using the 20 T, 195 mm Bitter magnet at the National High Magnetic Field Laborator...
Blade flap and chord bending and torsion moments are investigated for six rotors operating at transition and high speed: H-34 in flight and wind tunnel, SA 330 (research Puma), SA 349/2, UH-60A full-scale, and BO 105 model (HART-I). The measured data from flight and wind tunnel tests are compared with calculations obtained using the comprehensive analysis CAMRAD II. The calculations were made ...
the most important postharvest disorder of cut gerbera is stem bending disorder, which occurs below the capitulum. stem strength and lignification is one of important phenomenon and causes of gerbera stem bending. therefore, this experiment was conducted to evaluate the effects of salicylic acid (sa) on phenylalanine ammonia-lyase enzyme activity (pal), as an important enzyme in phenylpropanoid...
BACKGROUND Measurement of the bending stiffness a healing fracture represents a valid variable in the assessment of fracture healing. However, currently available methods typically have high measurement errors, even for mild pin loosening. Furthermore, these methods cannot provide actual values of bending stiffness, which precludes comparisons among individual fractures. Thus, even today, littl...
The use of shape memory polymer composites is growing rapidly in smart structure applications. In this work, an active asymmetric composite called "controlled behavior composite material (CBCM)" is used as shape memory polymer composite. The programming and the corresponding initial fixity of the composite structure is obtained during a bending test, by heating CBCM above thermal glass transiti...

We consider the swelling kinetics of layered structures. We focus on the case of triblock copolymer mesogels, although our results are applicable to other layered structures including clays. We assume the mesogels are swollen by a solvent that is good for the bridging block but poor for the non-bridging block. At long times the penetration front moves as in ordinary diffusion, i.e., as t1/2. At...
