Fatigue notch sensitivity and the notch size effect
International Journal of Fatigue, 2008Abstract 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.

Fatigue & Fracture of Engineering Materials & Structures, 1989
Abstract— The notch size effect (i.e. the decrease of the notched fatigue limit with increasing notch size for the same stress concentration factor) was quantitatively derived by describing the threshold conditions for the propagation of a short semi‐elliptical crack nucleated at the notch root.

Inverse size effects in un-notched and notched metallic glass thin films
Journal of Non-Crystalline Solids, 2022Abstract The sample size effect on the deformation behaviors of metallic glasses (MGs) attracts a lot of interest. Here, a series of molecular dynamics simulations have been performed on un-notched and notched MG thin films to fully investigate the influence of sample thickness on their fracture strengths and failure mechanisms.

Notch Effects in Carbon Matrix Composites
Journal of the American Ceramic Society, 1994The tensile properties of various carbon matrix composites, reinforced with C and SiC fibers, have been evaluated. The objective is to assess mechanics procedures for characterizing the influence of holes and notches. Interpretation has been attempted using large‐scale bridging mechanics, with linear elastic fracture mechanics as one limit and notch ...

Effects of finite notch width on the fracture of chevron – notched specimens
International Journal of Fracture, 1998The chevron notched three-point bend test specimen is often used for measuring the fracture toughness of brittle materials such as ceramics. Specimen sizes are often very restricted when testing advanced materials due to limited volume of material available or high material costs.

Abstract This chapter describes how notches affect the load-carrying capacity and fatigue life of materials under cyclic loads. It explains that stresses and strains can be three to four times higher in the vicinity of a notch, greatly accelerating fatigue damage.

The effects of notch geometry on fatigue life using notch sensitivity factor
Transactions of the Indian Institute of Metals, 2010The notch sensitivity of a material is a measure of how sensitive a material is to notches or geometric discontinuities. Notch sensitivity is influenced by many parameters such as notch geometry. Three types of notch geometries, V-shape, U-shape and -shape notches of various sizes are considered in this investigation.

Notch effect in low cycle fatigue
International Journal of Fatigue, 1999Abstract Life prediction in the low cycle fatigue regime in the presence of a geometric notch has been studied by two methods: – the `hot spot approach', by improving Dowling's method using more appropriate relationships between the elastoplastic stress and strain concentration factors and the elastic one than Neuber's rule, – the `critical volume ...
