joist. Notch strengthening or weakening relies on the existence of failure mode transition and materials exhibiting shear failure while subjected to tension will notch strengthen. Circumferentially notched bars are known to induce stress triaxiality: Shear deformation in the neck of such samples is confined by the shoulders, which gives rise to high A notch strengthening effect was found based on comparing the nominal flexural strength of the notched and un-notched specimens. From in-situ observations of the notched specimens, it was found Notch strengthening is well documented for metals and normally arises because the triaxial stress at the notch tip suppresses yield until the axial stress across the notch is considerably greater than the yield stress, Gy . From slip-line field theory, a value of 3Gy is generally taken as the The notch tensile strength (NTS) of a material is the value given by performing a standard tensile strength test on a notched specimen of the material.

We find that NSR is about 1.4, thus consistent with the value of … For example, NSR >> 1 means notch strengthening, while NSR 1 means notch weakening, and NSR ~ 1 indicated that the strength of material is insensitive to notch. Obviously, the nominal strength of NTS-1 with small K t = 2.23 is higher than that of the unnotched sample UNTS, showing a notch strengthening behavior with NSR a little larger than 1. Notch strengthening is well documented for metals and normally arises because the triaxial stress at the notch tip suppresses yield until the axial stress across the notch is considerably greater than the yield stress, Gy .

To simulate the actual damage caused by corrosion and the expansion of fatigue cracks, several researchers intentionally created notches of different geometry in midspan or other positions on … Experimental analysis of compressive notch strengthening in closed-cell aluminum alloy foam Antonia Antoniou a, P.R. Onck b, Ashraf F. Bastawros a,* a Aerospace Engineering and Mechanics, Iowa Anotch-strengthening effect was observed in the large-grained ice, with fracture stresses being up to 50% higher than that for unnotched samples of the same grain-size. This notch-strengthening effect diminished as grain-size decreased, disappearing at a grain-size of "'3 mm. Notch strengthening analysis of 316L stainless steel was carried out using electron backscatter diffraction (EBSD) and the finite element modeling (FEM) techniques.

Stubbins Nuclear, Plasma, and Radiological Engineering In recent experiments, evidence of notch strengthening has been found in one TiAl alloy under monotonic loading. The goal of this study is to fully explore this issue through tests on two cast alloys, one with a microstructure consisting of predominantly equiaxed gamma grains and the other having a fully lamellar microstructure.

Together they form a unique fingerprint. Austenitic stainless steel Engineering & Materials Science Irradiation Engineering & Materials Science We found that the studied MGs showed very unique notch behaviors: not only “notch strengthening” but also “notch toughening”, which means that both the nominal strength and plasticity of notched MG sample are larger than those of the smooth one. This is completely different from the conventional materials. Accompanied by this notch strengthening, the deformation mode shifts from shear banding to homogeneous deformation within the un-notched ligament, when the un-notched ligament length is less than twice the shear band width. As Kt becomes smaller, the notch strength ratio (NSR, which is the ratio of nominal ultimate tensile strength (UTS) of the notched sample to UTS of the unnotched sample) increases. When a ductile material such as UHMWPE is deformed in the presence of a notch, a phenomenon known as “notch strengthening” may occur. Due to this phenomenon, it is possible for the axial yield stress of the notched bar to be greater than that of the smooth bar.
