Fatigue notch sensitivity and the notch size effect

International Journal of Fatigue, 2008
Abstract It has long been known that the fatigue notch factor KF, given by σw0/σw, where σw0 is smooth specimen fatigue strength (R = −1) and σw is the fatigue strength of a notch-containing specimen, is less than the theoretical stress concentration factor, KT.

Notch strength and notch sensitivity of polymethyl methacrylate glasses

Materials Science and Engineering: A, 2003
In this study, attempts are made to obtain the approaches for quantitatively evaluating the notch sensitivity and the notch strength of polymethyl methacrylate (PMMA) glasses. Tension tests show that the unoriented PMMA glass is a low-ductility material and the oriented PMMA glass is a high-ductility one, and the orientation of PMMA glass greatly ...

Validation of Notch Sensitivity Factors

Journal of Verification, Validation and Uncertainty Quantification, 2019
An end-to-end example of the application of the procedures of verification, validation, and uncertainty quantification (VVUQ) is presented with reference to mathematical models formulated for the prediction of fatigue failure in the high cycle range. A validation metric based on the log likelihood function is defined.

Notch sensitivity and fractography of polyolefins

Polymer Engineering & Science, 1983
AbstractThe notch sensitivity of high‐density polyethylene (HDPE), polypropylene (PP), and polybutylene (PB) was evaluated using uniaxial tensile deformation and fractographic analysis. Each polyolefin was tested at relatively low and high molecular weights (MW). Only the lower MW HDPE was found to be clearly notch‐sensitive.

On the notch sensitivity of CuZr nanoglass

Journal of Applied Physics, 2014
Recently, nanoglass (NG) was found to exhibit a surprising homogeneous superplastic deformation behavior. However, how the presence of notch affects its mechanical properties remains unexplored. Here, we perform molecular dynamics simulations on a superplastic Cu50Zr50 NG containing a pre-existing notch under tensile loading, with focus on the notch ...

Fracture mechanics and notch sensitivity

Fatigue & Fracture of Engineering Materials & Structures, 2003
ABSTRACTA diagram valid for the analysis of the fatigue limit of cracks and notches centred in an infinite plate was recently proposed by the authors of the present work with the aim to make explicit the bridging at the fatigue limit between defect sensitivity (correlated to the length parameter a0, according to El Haddad–Topper–Smith's definition) and

The notch-sensitivity of ordered Zr3Al

Journal of Nuclear Materials, 1977
Abstract Experiments using notched tensile specimens have established that ordered Zr 3 Al is inherently notch sensitive. The notchsensitivity ratio, NSR, increases from ⋞0.7 at temperatures ⋞435 K to ∼-0.9 at temperatures ⋟575 K. Grain size and trace alloying with boron have negligible effects on the results.

The notch sensitivity of polymeric materials

Journal of Applied Polymer Science, 1976
Stress–strain tests were made on about five dozen polymeric materials using unnotched and notched specimens containing six different types of notches. Notches decrease the strength, but they decrease the elongation to break even more drastically in general.

Sensitivity of auditory nerve fibers to spectral notches

Journal of Neurophysiology, 1993
1. Listeners use direction-dependent spectral cues introduced by the torso, head, and pinnae to localize the source of a sound in space. Among the prominent direction-dependent spectral features in the free field-to-eardrum transfer function are narrow regions of low acoustic energy referred to as spectral notches.
