NOTCH SENSITIVITY OF STEELS

1953
Abstract : The portion of the room-temperature notch brittleness of high-strength steels which is attributed to transition-temperature (T sub tr) behavior was determined. The linear dependeance of the notch strength on the notch depth at higher tempering temperatures permitted an evaluation of notch sensitivity in terms of ductility changes.

Notch Sensitivity of First‐Year Sea Ice

Journal of Engineering Mechanics, 1993
Tests were carried out in Resolute NWT, Canada, (75°43″\NN, 95°04″\NW) on first-year sea ice to determine for the first time the notch sensitivity of first-year sea ice. A displacement feedback control was used on a soft portable testing frame to apply a calculated strain rate of 10\u-³s\u-¹ at the extreme tensile fiber of the beam. An ice beam 0.1 m ×

Notch and Defect Sensitivity of Adi in Torsional Fatigue

2008
Recently Atzori et al. [1,2] analysed the sensitivity to defects and to standard notches in axial fatigue of metallic materials commonly adopted in manufacturing engineering components and structures, like steels and aluminium alloys. As a result of the proposed approach, the effect of any kind of geometrical discontinuity on the fatigue limit can be ...

Notch sensitivity of polymethyl methacrylate

Polymer Mechanics, 1973
It is shown that acrylics have a notch sensitivity determined by the nature of the state of stress produced by the loading.

Notch sensitivity of polycarbonate and toughened polycarbonate

Journal of Applied Polymer Science, 2003
AbstractNotch sensitivity, the effect of a notch radius on the impact behavior of polycarbonate and rubber‐toughened polycarbonate, is investigated by using a model based on the slip‐lines field theory. Impact strength, determined by the Charpy impact test, was found to increase drastically with an increasing notch radius for pure polycarbonate ...

Notch sensitivity of structural steel with silicon

Metal Science and Heat Treatment, 1973
1. An increase of the silicon or carbon content substantially increases the notch sensitivity of heat treated silicon steel, which is associated with an increase of the ductile-brittle transition temperature. 2. Analysis of the increase in the ductile-brittle transition temperature confirms the conclusion that it is expedient to use ...

Notch sensitivity of aliphatic polyketone terpolymers

Journal of Applied Polymer Science, 2003
AbstractThe notch sensitivity of aliphatic polyketone (PK) terpolymers was investigated in this article. The notch‐tip radius was varied between the size of an actual propagating crack tip of 1–2 μm and the largest notch tip of 1000 μm radius. The larger notch‐tip radii (1000–15 μm) were milled into the polymer. The smallest notch‐tip radii of 2 and 15

On the notch sensitivity of CuZr metallic glasses

Applied Physics Letters, 2013
Atomistic simulations are performed to study the effects of size and shape of a superficial or internal notch on the strength and failure mechanism of CuZr metallic glass (MG) under tensile loading. Our results show that plastic deformation originating at the notch root reduces the stress concentration there and leads to a notch-insensitive normalized ...

Notch sensitivity of fiber-reinforced ceramics

International Journal of Fracture, 1993
Crack bridging from an elliptical hole in fiber-reinforced ceramic composites is studied. For some fiber-reinforced ceramic composites, matrix toughness is much less than the toughness gained in the bridging zone, i.e. the bridging zone runs across the entire width of a specimen at a small load. In such case, load-carrying capacity of the specimen only

Stress Notch Sensitivity With Eccentric Holes

Journal of Fluids Engineering, 1948
Abstract The tension strength of several cross sections containing holes of several diameters in several positions of eccentricity have been determined experimentally for aluminum alloys 24S-T, 75S-T, and 14S-T. A mathematical expression is suggested for the relationship between strength, hole size, and eccentricity of hole. The relative
