Analysis of Strength Variation in Glass Due to Ion Exchange
… resulting Modulus of Rupture (MOR). Statistical analysis techniques and Weibull analysis were used to study the variations which occur within and between strength distributions of each sample group. A smaller sampling of test groups was subjected to fractographic analysis to study the effect of …

The Effect of Cracks and Geo-Morphology on Evaporation from Clay Soils.
… using a laser scanner, as well as by pixel analysis of surface photographs. The drying test has shown that crack surfaces contributed at most to 6% of total evaporation before de-saturation and up to 63.4% after de-saturation. Results have also shown that Chertkov's model could model crack …

Structure and properties of carbon fibre reinforced aromatic thermoplastics
… particle size over the size range examined. Fractographic analysis of this phenomenon revealed several toughening mechanisms: Polyetheretherketone (PEEK) rich zones act as crack arresters; fibre bundle and particle bridging of the crack increase the work to fracture. Impact toughness is …

Fretting fatigue Behaviour of Inconel 718 at room and high Temperature
… loads on the fatigue life of the material. A fractographic analysis of the tested specimens was subsequently conducted using scanning electron microscopy (SEM), which enabled the identification of distinct regions on the fracture surface, as well as the establishment of correlations between …

Effects of Voids on Delamination Behavior Under Static and Fatigue Mode I and Mode II
… and fatigue loading was investigated. Finally, fractographic analysis (using optical and scanning electron microscopy) was conducted.The results showed that voids leads to slight reduction in static modes I and II interlaminar fracture toughness. In addition, voids lead to a decrease in modes I …

The effect of repetitive firing cycles on physical and optical properties of zirconia reinforced lithium silicate ceramics
… absorption coefficient. Weibull parameters and fractographic analysis also were investigated. The results showed that repetitive firing cycles reduced e.max® and Vita Suprinity’s® translucency, but not that of Celtra® Duo, which showed no significant difference. All materials of greater …

Stress corrosion cracking and crack tip characterization of Alloy X-750 in light water reactor environments
… and 3D Atom Probe Tomography (APT). The SEM analysis was focused on the fractographic analysis and crack-propagation mode. The crack was observed to propagate adjacent to grain boundary carbides (pseudo-intergranular) and along a boundary with high coherency where no carbides were present …

Influencia de la radiación ultravioleta en el comportamiento mecánico y en la microestructura de las fibras de seda de araña
… silk. The characterization was completed with a fractographic analysis of fibers subjected to different irradiation times. Microstructural variation generated by UV radiation were analysed with X ray diffraction as well as Raman spectroscopy. The combination of both techniques allowed a complete …
