“…Numerous studies have shown that the true contact area has an almost linear relationship with the residual stress and increases with increasing compressive stress, while it decreases with increasing tensile stress. 31,35,37,62 The different variation of true contact area with residual stresses is due to the fact that compressive stresses tend to increase the pile-up amount, thus increasing the true contact area, while tensile stresses gives an opposite effect to decrease the true contact area.…”

Instrumented indentation, which is also known as nanoindentation or depth-sensing indentation, is increasingly being used to probe the residual stresses of materials including bulk solids, thin films, and coatings. The residual stresses are proved to have significant effects on various nanoindentation parameters such as hardness, loading curve, unloading curve, pile-up amount around indentation, and true contact area. By analyzing these parameters, numerous methods are developed to evaluate the residual stresses of materials in recent years. This article reviews six commonly used models which determine residual stresses from analyzing load-depth curves, as well as indentation fracture technique which is based on the classical fracture mechanics. Emphasis is placed on the principle, application and limitation of each nanoindentation method.

“…For the tempered glass, the exact Poisson's ratio of the surface region with compressive stress is unknown 4,30 ; thus, we use the reduced modulus, rather than elastic modulus here. Also, note that the Oliver‐Pharr model is based on the projected area ( A c ) calculated from a contact depth ( h c ) which is estimated from h max , P max , and stiffness ( S ) of the P ‐ h curve (as marked in the top panel of Figure 4A as an example) assuming that the material is homogeneous and has no stress and its response is fully elastic; thus, it does not work well for the material with an internal stress gradient 44–46 . Then, the reduced modulus and hardness calculated from the P ‐ h curves of the tempered surfaces must be taken as apparent values predicted from the Oliver‐Pharr model assuming no internal stress, instead of true values which can be obtained only when the real contact area is known.…”

Thermal tempering is an industrial process widely used to make soda lime silica (SLS) glass panels stronger and tougher. During the tempering process, the upper and bottom sides of the glass may experience different cooling rates, and thus, their properties could be different. This study characterized changes in surface composition and subsurface glass network structures as well as indentation and wear resistance properties of the air‐ and tin‐sides of 6‐mm‐thick SLS window panels faced toward the upper and sliding roller sides during thermal tempering. The results showed that although the chemical and structural differences detected with X‐ray photoelectron spectroscopy and specular reflection infrared spectroscopy are subtle, there are large differences in nanoindentation behaviors and mechanochemical wear properties of the SLS glass surface. The findings of this study provide further insights into the performance difference between the air‐ and tin‐sides of the SLS glass panel treated with thermal tempering.

The short carbon fiber reinforced 2024 Al composites were fabricated through powder metallurgy. The effect of short carbon fiber content on the interfacial microstructure and fracture behavior of the composites at different temperatures were investigated. The results showed that the dislocation accumulation was formed in the aluminum matrix due to the thermal expansion mismatch between carbon fiber and aluminum matrix. With the testing temperature increasing, the size of interfacial product Al4C3 and precipitates Al2Cu became larger, and the segregation of Al2Cu was found coarsening around Al4C3. The addition of short carbon fiber improved the hardness and modulus of the aluminum matrix in the vicinity of the interface between carbon fiber and aluminum matrix. Compared to the matrix 2024 Al, the yield strength and ultimate tensile strength of the composites first increased and then decreased with increasing short carbon fiber content at room temperature 423 Kand 523 K. The fracture surface of the composites at room temperature was characterized by shear failure of fiber, while the interface debonding and fiber pulled-out became predominant fracture morphologies for the fracture surface at increased temperatures.
