The failure mechanisms of Oxide-Oxide ceramic matrix composites AS-N610 were studied at both room temperature and high using tensile fatigue tests with without lateral laminar notches. unnotched coupons had an average strength 423 MPa elastic modulus 97 GPa showing a perfect behaviour whereas the notched samples shown similar 425 (98 GPa) revealing pseudo-ductile behaviour. A reduction in oxide...

Power law distributed fluctuations are known to accompany \emph{terminal} failure in disordered brittle solids. The associated intermittent scale-free behavior is of interest from the fundamental point view as it emerges universally an intricate interplay threshold-type nonlinearity, quenched disorder, and long-range interactions. We use simplest mean-field description such systems show that th...

In this paper, the microstructure, the room-temperature and high-temperature tensile mechanical properties of monolithic TA15 alloy and TiB whisker-reinforced TA15 titanium matrix composites (TiBw/TA15) fabricated by vacuum hot-pressing sintering were investigated. The microstructure results showed that there were no obvious differences in the microstructure between monolithic TA15 alloy and Ti...

The failure of resistance spot welds through the fusion zone along sheet/sheet interface (i.e., interfacial failure) is critical for automotive crashworthiness. This paper investigates effect hardness on behavior during tensile–shear test. AISI 1040 medium carbon steel, producing a high level mismatch welding, was selected as base metal. By ex situ tempering heat treatment, various levels are a...

In this article, failure and fracture mechanisms in an aluminum alloy (which has been used in diesel internal combustion engines), with and without ceramic thermal barrier coatings, have been investigated under isothermal and non-isothermal fatigue loadings. In this research, the base material is an aluminum-silicon-magnesium alloy and the thermal barrier coating includes a metallic bond coat l...
