“…Additionally, the method has also been used to compute mechanical properties of materials. 13,14 These studies and many others have shown that the accuracy is satisfactory and often better than can be expected with traditional techniques. The accuracy depends on the resolution of the camera used, the distance from camera to specimen, and by the fines and details of the pattern on the surface of the test specimen.…”

Knowledge about the plastic behavior of reinforcement steel bars in reinforced concrete (RC) structures is important, especially for seismic design. This paper presents the results of experimental tests where the main aim was to map the plastic deformations of long ribbed reinforcement bars, both in the axial and lateral directions, in order to provide useful information about the behavior of reinforcement bars inside concrete. The study showed that the digital image correlation (DIC) technique is very suitable for this kind of tests. The uniaxial stress–strain curves for side‐by‐side and different gauge lengths (1d, 3d, 5d, 10d) were identical all the way to the max stress, but after that the segment including the neck dominated the strain development. The Poisson's ratio increased rapidly during the yielding phase to 0.44–0.49 and was constant all the way to rupture. The location of the neck could be predicted at the end of the yielding phase.

The influence of nanofiller on the tensile and surface charge properties of Al/Epoxy nanocomposite materials is investigated with respect to their structural composition. The formation of conductive network nearing the percolation limit with the addition of nanofiller has strongly influenced the mechanical and electrical characteristics of nanocomposites. The digital image correlation technique is employed to acquire the strain variation at the distinct locations on the tensile specimen. The loaddisplacement, as well as shape deformation, were analysed for the various nano filled composites. The improved tensile characteristics were achieved up to certain wt% of filler addition, beyond which the load and time required for the material fracture were reduced drastically. Likewise, the addition of filler up to 5 wt% has shown the improved charge decay characteristics viz. quicker charge decay and enhancement in shallow energy states under the applied DC voltage. The direct analogy in mechanical and electrical characteristics was formulated in terms of structural composition (defects, additives and filler) of respective materials.

“…The applications of electrical steel sheet were determined by the performances of the coating, which influenced the quality and service life of the motors. The compatibility between water‐soluble resin and nano‐particle was a problem for the water‐based composite electrical steel coating. So it is a great chance to deal the problem, as a result the nano‐particles were always modified to enhance the compatibility , such as modified by silance coupling agent , titanate coupling agent, or grafted by polymer .…”

The composite coating with glycine modified SiO2 used as the fillers was prepared in this study. The methods of glycine modify SiO2 were discussed, the modified results were characterized by FTIR, XRD, XPS, and TEM. The results of the comparison among the coating filled with SiO2 modified by different methods indicated that glycine grafted could enhance the compatibility between the polyester solvent and the SiO2 particles. The curing speed of the coating was not changed, the insulation performances were enhanced and the mechanical properties were not affected by the glycine modified, and the mechanism of the enhancement was the reunite of the particles was reduced and the wettability against polyester was enhanced.
