“…Although values of KC calculated by Eqs. ( 23), ( 26) - (31) are smaller than the reasonable value (i.e., 3.1 MPa·m 1/2 ), the empirical constants of those equations can be simply modified to give reasonable value of KC: the prefactor 0.035 in Eq.

Mechanical characterization of dielectric ceramics, which have drawn extensive attention in wireless communication, remains challenging. Micromechanical properties with microstructures of dielectric ceramic BaO-Sm2O3-5TiO2 (BST) were assessed by nanoindentation, microhardness, and microscratch tests under different indenters, along with X-ray diffraction, scanning electron microscopy, and Raman spectroscopy. Accurate determination of elastic modulus (i.e., 260 GPa) and indentation hardness (i.e., J u s t A c c e p t e d 16.2 GPa) of brittle BST ceramic by instrumented indentation technique requires low loads with little indentation-induced damage. Elastic modulus and indentation hardness were analyzed by different methodologies such as energybased and displacement-based approaches, and elastic recovery of Knoop imprint. Consistent values (about 3.1 MPa·m 1/2 ) of fracture toughness of BST ceramic were obtained by different methods such as Vickers indenter-induced cracking method, energy-based nanoindentation approaches, and linear elastic fracture mechanics-based scratch approach with a spherical indenter, demonstrating successful applications of indentation and scratch methods in characterizing fracture properties of brittle solids. The deterioration of elastic modulus or indentation hardness with the increase in indentation load is caused by indentation-induced damage, and can be used to determine fracture toughness of material by energy-based nanoindentation approaches, and the critical void volume fraction is 0.27 (or 0.18) if elastic modulus (or indentation hardness) of the brittle BST ceramic is used. The fracture work at the critical load corresponding to the initial decrease in elastic modulus or indentation hardness can also be used to assess fracture toughness of brittle solids, opening new venues of application of nanoindentation test as a means to characterize fracture toughness of brittle ceramics.

“…The picklability of the oxide scale on steel substrate assess via an immersion test [25,26]. The scale adhesion has been measured by various techniques such as an indentation test [27,28], the tensile test [29][30][31][32][33]. This study aimed to assess the effect of Si content in the hot-rolled steel on the mechanical adhesion of the oxide scale by using a tensile testing machine with an observation set (CCD camera).…”

In the hot-rolling process, steel was subjected to high temperatures which results in the formation of an oxide layer called scale. The oxide scale can be affected to the surface characteristic of the hot-rolled steel product. The scale must be completely removed from the surface of the steel before further processing. This research aimed to examine the adhesion behavior of scale on hot-rolled steel with different silicon contents (0.01, 0.12, 0.18, and 0.29 wt%) using a tensile testing machine with an observation setup. The results showed that the scale thickness decreased with increasing silicon content in the range of 9 µm to 12 µm. The scales were composed of hematite and magnetite. The results of the tensile test showed that the strain initiating the first spallation and the mechanical adhesion energy tend to increase with increasing silicon content. However, it decreased by 0.29 wt% Si hot-rolled steel. This result indicates that scale was difficult to remove after the hot rolling process for higher Si-containing steel.

“…However, VO 2 is mostly applied in the form of a thin film bonded to the substrate in practical products. One of the main obstacles that may lead to functional failure is the residual stress, which may cause significant changes in shape or even produce lamination, buckling, and cracks [ 7 ].…”

The buckling, de-lamination, and cracking of the thin film/substrate system caused by thermal stress is the main obstacle for functional failure. Moreover, the thermal stress of vanadium dioxide (VO2) thin film may be more complicated due to the stress re-distribution caused by phase transition. Therefore, the thermal stress of VO2 thin films deposited on four substrates with different materials (fused silica, silicon slice, sapphire, and glass) has been studied by finite element method in the present work. The influences of external temperature, substrate, and interlayer on thermal stress were analyzed. It was found that the substrates can greatly affect the thermal stresses, which were mainly caused by the mismatch of coefficient of thermal expansion (CTE). The thermal stress had a linear relationship with the external temperature, but this tendency would be redistributed or even change direction when phase transition occurred. The simulated results were in tandem with the analytical method. Meanwhile, the radial stress and shear stress distribution under the influence of phase transition were calculated. In addition, the reduction of thermal stress and shear stress showed that the appropriate interlayer can enhance the adhesive strength effectively.
