The stress-induced martensitic (SIM) transformation of NiTi shape-memory alloy wires has been studied as a function of the maximum strain induced during tensile deformation at impact and quasi-static strain rates. The SIM transformation stresses are higher at impact than at quasi-static strain rates...
The interior of nanoscale crystals experiences stress that compensates for the capillary forces and that can be large, in the order of 1 GPa. Various studies have speculated on whether and how this surface-induced stress affects the stability and plasticity of small crystals. Yet, experiments ...
Stress relaxation data on the cold-drawn wires are presented graphically showing a semilogarithmic relationship. The linear function of the logarithm of the strain rate in these wires at a given temperature is also represented graphically showing that the amount of the thermal flow stress component ...
In order to develop a Nb3Sn coil using a react and wind method, it is important to clarify the influence of bending strain because the superconducting characteristics of Nb3Sn are very sensitive to stress and strain. We investigated the effect of prebending strain εpb, which means repeated ...
Stress-strain effects in alumina-Cu reinforced Nb_3Sn wires fabricated by the tube process 喜欢 0 阅读量: 5 作者:S Murase,S Nakayama,T Masegi 摘要: In order to fabricate a large-bore, high-field magnet with achieves a low coil weight and volume, a high strength compound superconducting ...
84These sensors can be applied over the joint as a sleeve to monitor the stress and strain on the elbow, anterior cruciate ligament (ACL), medial collateral ligament (MCL), or posterior cruciate ligament (PCL). In 2015, 25% of active major league baseball (MLB) pitchers and 15% of ...
Tensile tests were performed on two different transverse standard tensile specimens at room temperature, and the stress–strain graph is plotted in Figure 12. Two fractured tensile samples under examination, as shown in Figure 12a, initiated the fracture next to the weld zone in the HAZ of the ...
A deviation in the stress–strain curve is already obvious after ≈1% normalized deflection. Further, the saturation level as well as saturation behavior are not captured correctly. This is due to a bending-dominated deformation mode which cannot be properly captured by the linear element ...
With the dielectric weakened, voltage overstress conditions can occur even though an applied voltage may be within a device’s rated limits. In mild cases, the only symptoms may be an increased leakage current and elevated device temperatures for a time, until the device self-heals. In severe...
We would like to stress, however, that limitations and weaknesses of individual modalities may not be overcome by monitoring many physiological parameters. Continuing the search for limitations associated with the individual modalities is therefore warranted so as to provide the best possible patient ...
