“…8 show the fitting results of an experimental loading curve based upon the calculation flow chart using the reverse analysis algorithm described in Refs. [16][17][18], where The material parameters obtained from the indentation test data are shown in Table 2, and those of stress and strain obtained from the flow chart are shown in Table 3. In Tables 2 and 3, m is Poisson's ratio, h r is the residual depth of indentation, h m is the maximum depth, r 0.033 is the critical stress, E * is the equivalent modulus, A is the projection contact area of indentation and P ave is the average contact pressure.…”

“…At present, research based on the nanoindentation test have mainly focused on the micromechanical performance and machinability of hard and brittle materials such as optical crystals; the mechanical properties and biocompatibility of biomedical and biomimetic materials; the mechanical properties and service conditions of thin films and potential microsensor and microsystem components; and, finally, the contact and friction characteristics of information storage media [12]. In addition, the nanoindentation test itself has been the subject of research to determine the influence that the shape and dimensions of the head and specimen materials have upon the test results [13]; how to process the indentation experimental data and the load-displacement curve and to best fit the loading and unloading curves [14,15]; and on the computational methods for the stress-strain curve based upon indentation experimental data [16][17][18]. Zhao et al [19] performed nanoindentation tests and analyses on soda lime silicate glass, and introduced the concept of the relatively-elastic recovery rate.…”

In this paper, the mechanical properties of electronic glass are tested using a combination of the Vickers indentation test and a multiple-loading nanoindentation test to obtain the elastic modulus, Poisson's ratio and hardness values. The basic mechanical property parameters of the electronic glass and its stress-strain curve are found using atomic force microscopy analysis of the indentation morphology. The critical pressure and depth for crack initiation and the corresponding load and depth can be obtained during vertical loading on the electronic glass. When cracks extend to the surface, the results show that the electronic glass is isotropic. Several loading cycles causes a fatigue effect on the surface of the electronic glass, which decreases its elastic-plastic response. While the loadings are increasing, the elasticplastic response rates are decreasing bur it rends stability finally. These results can provide a reference and guide for micro machining and surface microstructure machining of electronic glass.

In order to increase the flexural strength and to adjust the coefficient of thermal expansion (CTE), TiO 2 was introduced into Li 2 O-Al 2 O 3 -SiO 2 (LAS) glass-ceramics to satisfy LTCC applications. The effects of TiO 2 addition on the microstructure, thermal, mechanical and electrical properties were studied. The results showed that the crystal phases were composed of Li 2 OAl 2 O 3 7.5SiO 2 (major), as well as TiO 2 and CaMgSi 2 O 6 (minor). The crystal phase TiO 2 having higher CTE value could appropriately increase the CTE value of LAS to fit the silicon and remarkably improve the flexural strength of LAS glass-ceramic with low CTE. The dielectric and insulating properties also strongly depended on the amount of TiO 2 . LAS glass-ceramic sintered at 800°C with high performances was achieved in the case of 1 wt% TiO 2 : a = 2.56 9 10 -6 /°C, r = 151 MPa, e = 6.8, tand = 1.731 9 10 -3 , q = 8.29 9 10 10 X cm.
