V-notch to Prevent Sliding of Crimpable Hook
Orthodontic Journal of Nepal, 2015 En-mass retraction of anterior teeth most commonly involves the use of crimpable hooks which often dislodge when retracting force is applied. A V-notch distal to the hook may prevent such sliding when sandblasting and dental adhesives are not ...

Critical applied stresses for a crack initiation from a sharp V-notch [PDF]
Fracture and Structural Integrity, 2014 The aim of the paper is to estimate a value of the critical applied stress for a crack initiation from a sharp V-notch tip. The classical approach of the linear elastic fracture mechanics (LELM) was generalized, because the stress singularity exponent ...

Centrifugal fan V-Notch cutoff [PDF]
The Journal of the Acoustical Society of America, 1981 The sound from two 5600 HP induced draft fans at a 500-MW coal-fired power plant was a source of community annoyance. Each fan was retrofitted with a V-notch cutoff designed to reduce the noise generated at the blade passage frequency and its harmonics.

Effects of initial imperfection and mesh resolution on wrinkle and crease analyses
Nihon Kikai Gakkai ronbunshu, 2021 This study investigates the effects of initial imperfection and mesh resolution on the wrinkling and creasing. Finite element analyses are conducted to simulate compression behaviors of an incompressible Neo-Hookean elastic plane with a V-shaped notch as

Creep behavior of V-notched components
Frattura ed Integrità Strutturale, 2017 Geometrical discontinues such as notches play a significant rule in structural integrity of the components, especially when the component is subjected to very severe conditions, such as the high temperature fatigue or creep. In this paper, a generalized form of the existing notch tip creep stressstrain analysis method developed by Nuñez and Glinka, is ...
