Notch (In)Sensitivity of Aluminum Matrix Syntactic Foams [PDF]

Materials, 2019
Aluminum alloy (Al99.5 or AlSi12)-based metal matrix syntactic foams (MMSFs) were produced by pressure infiltration with ~65 vol % Globocer filler (33 wt % Al2O3, 48 wt % SiO2, 19 wt % Al2O3∙SiO2). The infiltrated blocks were machined by different geometry tools in order to produce notched samples.

A Consideration on the Notch Sensitivity of Steel

Journal of Zosen Kiokai, 1961
The nominal yield stress was measured on centrally perforated plate specimen which was machined from various steels with a wide range of transition temperature measured by V-Charpy test. The load for yielding was determined from the stress-strain curve which was obtained using SR 4 gauge put in touch with the circumference of the hole.

Notch sensitivity of mammalian mineralized tissues in impact [PDF]

Proceedings of the Royal Society of London. Series B: Biological Sciences, 2004
The toughness of bone is an important feature in preventing it from fracturing. We consider the notch sensitivity in impact, and the associations between brittleness, notch sensitivity and post-yield energy absorption of mammalian mineralized tissues. Specimens of bone-like tissues covering a wide range of mineralization were broken, either notched or ...

Assessing the Notch Sensitivity of High Strength Wires

Latin American Journal of Solids and Structures
High strength wires, which have a poor notch sensitivity performance, are currently been used on many offshore applications where high stresses without yielding are demanded. To assess these wires notch sensitivity, an integrated approach was implemented.

Uif, a large transmembrane protein with EGF-like repeats, can antagonize Notch signaling in Drosophila. [PDF]

PLoS ONE, 2012
BACKGROUND:Notch signaling is a highly conserved pathway in multi-cellular organisms ranging from flies to humans. It controls a variety of developmental processes by stimulating the expression of its target genes in a highly specific manner both ...

Pulmonary Doppler Notch Pattern in Relation with Pulmonary Vascular Resistance Index in Patients with Atrial Septal Defect

Majalah Kardiologi Indonesia, 2021
Background: Atrial septal defect (ASD) potentially causes pulmonary hypertension (PH) and increased pulmonary vascular resistance (PVR). In previous studies, pulmonary Doppler notch was evident in patients with high PVR.

On the Notch-Sensitivity and toughness of A Ceramic Composite [PDF]

Advanced Composites Letters, 1992
A Nicalon TM/SiC fabric (8-harness satin) reinforced alumina matrix (CMC) was loaded in tension to fracture. A coating on the surface of the fibre reduced the strength of the fibre-matrix bond, increased the toughness of the CMC by more than 3 times, and raised the unnotched strength by more than 2 times.
