TL;DR: In this article, the effects of void growth and interaction and specimen necking on material failure have been investigated for a single material cell, with a discrete cluster of four voids, where geometrical parameters have been varied to result in seven unique periodic and random void arrangements.

TL;DR: In this article, the effects of interfacial tension, manipulated by the use of surfactants, and electric field strength on the formation of secondary droplets are investigated, and the results are useful for optimizing the design of the electro-coalescence systems.

TL;DR: In this paper, high quality Bi2Sr2CaCu2O8+δ single crystals have been grown successfully by the traveling solvent floationg zone (TSFZ) method with the necking technique.
Abstract: High-quality Bi2Sr2CaCu2O8+δ single crystals have been grown successfully by the traveling solvent floationg zone (TSFZ) method with the necking technique. The crystallinity was characterized by a double-crystal X-ray diffractometry. The full-width at half maximum (FWHM) of the rocking curve was improved from 120 arcsec to 75 arcsec by the necking technique using a single crystal seed.

TL;DR: In this article, Mg-based metallic glass wires were produced via the melt-extraction technique and their mechanical properties were evaluated by carrying out tensile tests on electrochemically polished dogbone-shaped wire samples and their reliability was estimated using Weibull analysis.

TL;DR: In this article, the effects of pre-strain on plane stress ductile fracture in a 70/30 alpha brass Austral 207 have been studied using the deep-edge-notched tension (DENT) specimens.
Abstract: The effects of pre-strain on plane stress ductile fracture in a 70/30 alpha brass Austral 207 have been studied using the deep-edge-notched tension (DENT) specimens. The amount of pre-strain varies between 5 and 35%. It is found that both the specific essential work of fracture (w
e) and the critical crack opening displacement (δc) decrease with increasing pre-strain. A simple theory for estimating the specific essential work of fracture in the presence of pre-strain is suggested and it gives good agreement with experimental results. Elongations to fracture in the DENT specimens are also predictable from a simple deformation analysis which considers the plastic elongations due to crack initiation, crack propagation and final stretch of a ligament that has reached a necking strain equal to that in a simple plain tension test. Micro-hardness measurements show that the strain localization is more intense near the fracture surface as the pre-strain level is increased and this is suggested to be an explanation for the low δc values obtained in pre-strained specimens.
