Critical applied stresses for a crack initiation from a sharp V-notch [PDF]

open access: yesFracture 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 ...

The effect of groove and notch tip angles on testing fracture toughness by SEVNB method: models and experimental validation

open access: yesJournal of Asian Ceramic Societies, 2023
The single-edged V-notch beam (SEVNB) method is considered as an effective method for evaluating the fracture toughness values of brittle materials. In this method, it is assumed that the V-notch is a natural crack.

Effects of initial imperfection and mesh resolution on wrinkle and crease analyses

open access: yesNihon 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

Experimental method to predict scour characteristics downstream of stepped spillway equipped with V-Notch end sill

open access: yesAlexandria Engineering Journal, 2021
To protect the dam body and downstream area, spillways should be built. Because the difference in water level upstream and downstream spillways is usually very big, energy dissipation facilities should be introduced.

Sequential Notch signalling at the boundary of fringe expressing and non-expressing cells. [PDF]

open access: yesPLoS ONE, 2012
Wing development in Drosophila requires the activation of Wingless (Wg) in a small stripe along the boundary of Fringe (Fng) expressing and non-expressing cells (FB), which coincides with the dorso-ventral (D/V) boundary of the wing imaginal disc.
