“…Our previous works [10][11][12] related to laminated ZrB 2 -SiC ceramics with strong interfaces indicated that mechanical properties are significantly enhanced by the presence of residual surface compressive stresses [13,14]. The present work aims at investigating the effect of geometrical structure parameter of laminated structures on the thermal shock resistance and action mechanism of residual surface stresses on the thermal shock behavior of laminated ZrB 2 -SiC ceramics.…”

The thermal shock behavior of laminated ZrB 2-SiC ceramics with strong interfaces has been investigated by indentation-quench method through experiments and modeling, and was compared with that of a reference monolithic ZrB 2-SiC ceramic. The residual stress formed in the layers of laminated ZrB 2-SiC ceramics was also quantified by indentation technique. Results obtained by indentation-quench tests show that the monolithic and laminated ZrB 2-SiC ceramics present a similar crack growth behavior with increasing temperature difference. Nevertheless, the critical temperature difference, ΔTc, of laminated ZrB 2-SiC ceramics is much higher than that of the monolithic ZrB 2-SiC ceramic. A theoretical model considering all the stress intensity factors at the surface crack tip during thermal shock was established to analyze the mechanism of indentation thermal shock, which is in good agreement with the

“…During the delay of 70 μs in the rise time for the reflected and transmitted stress waves, almost none of the wave reflects into the incident bar but instead is either transmitted directly into the transmitted bar or is trapped in the specimen. It should be noted that the reflected waves showed a relatively large fluctuation that may be attributed to defect formation in specimens [21] . The engineering stress history of the specimens calculated from the tested data at various strain rates are shown in Fig.…”

SiC/B4C composite was obtained using the reaction sintering method with Si infiltration, which exhibited excellent mechanical properties. The dynamic compressive response was investigated using a Split Hopkinson pressure bar at high strain rates ranging from 0.4×103 to 1.2×103 s-1. The results show that the dynamic strength of the SiC/B4C composite obtains a peak value at a strain rate of 1000/s, while its strain increased continuously with increasing strain rate. The dynamic loading mode of SiC/B4C composite exhibited three deformation regions, including an inelastic deformation region, rapid loading region and failure region. The dynamic failure mode of SiC/B4C composite depended upon the strain rate.

“…Through this way, the toughness and fracture work of ceramics is greatly enhanced. Other processes of fabricating ceramics with strong or weak interfaces are developed, for example tape casting and addictive manufacturing [3][4][5][6][7] . Adopted by all these method, one basic mechanism is to enhance the crack deflection between interfaces.…”

The uncertain ballistic effects and reliability optimization design of the ceramics composite armors are investigated. Considering the material uncertainty, the ballistic penetration process is analyzed through simulation model. The effects interlayer SiC mass fraction and the matrix thickness gradient ratio are discussed. The optimal parameters of both material and structure are obtained through reliability design methods and verified through ballistic experiments. The results show that the standard deviation can be reduced when interlayer SiC mass fraction increases. The ballistic depth can be reduced by increasing the gradient ratio. Through optimization, the ballistic reliability of the ceramic composite armor is improved.
