Such a unified scenario, analogous to the well-known Lindemann criterion for crystal melting, provides insight into the structural origin of the strain-induced glass-liquid transition. 展开 关键词: Metallic glasses Thermodynamics and statistical mechanics Structural modeling: serial-addition models computer...
The regularities of temperature-and strain-induced order-disorder phase transitions are determined from analyzing X-ray diffraction data. The results obtained are used to reveal common features in order-disorder transformations induced under energy actions of different types. It is established that, in ...
A transition in ductile fracture appearance from a cup-cone fracture at room temperature to shear fractureat cryogenic temperature is observed and correlated to deformation behavior and micromechanisms (void nucleation and strainlocalization) of fracture. The flow stresses, fracture stresses, and strain ...
However, to increase the temperature-induced strain effect of FBG at cryogenic temperatures, a secondary material that has a higher thermal expansion coefficient than silica must be coated on FBG. So, the coated materials must have a higher thermal expansion coefficient to gain good thermal strain ...

High-strain-rate micromechanical impact experiments were carried out using laser-induced particle impact tests, detailed in Methods. Spherical alumina microparticles, roughly 12.5 ± 1 μm in size, were chosen as impactors onto copper substrates owing to their much higher hardness (static hard...
Strain/Temperature Discrimination Using Combined Fiber Bragg Grating and Long Period Grating Sensors We describe a novel sensor which uses the difference in response of fiber Gragg gratings and a long period fibr grating to discriminate between temperature and strain induced wavelength shifts.

For the next generation of wearable health monitors, it is essential to develop stretchable and conformable sensors with robust electrical performance. These sensors should, in particular, provide a stable electrical output without being affected by external variables such as induced strain. Here, we ...
3.1.2. Effect of heating on the elastic modulus, failure strain and damage factor Elastic modulus is used to describe the deformational behaviour of a material, and it indicates the resistance offered by the material to the induced deformation. With increasing temperatures, Young's modulus of san...
