Experimental conditions affecting the measured fracture toughness at the microscale: Notch geometry and crack extension measurement

Materials & Design, 2020
Experimental fracture mechanics at the microscale became an indispensable tool for understanding and developing advanced material systems. In case of linear elastic fracture mechanics, stringent requirements are typically only warranted for very brittle ...

The use of thermally expandable microcapsules for increasing the toughness and heal structural adhesives

Fracture and Structural Integrity, 2013
In this research, the effect of thermally expandable microcapsules (TEMs) on mode I fracture toughness of structural adhesives were investigated. The single-edge-notch bending (SENB) test was used.

Numerical estimation of a Mode III fracture Mechanics parameter for three-dimensional elliptic boundary value problems with a crack singularity

Partial Differential Equations in Applied Mathematics, 2021
In this study two spatial problems of solid bodies with a surface crack singularity (V-notch) are examined. These are problems in the domain of linear elastic fracture Mechanics which are reduced to Laplace equation problems by considering a Lamé ...

Application Limit of Linear Notch Mechanics.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 1995
An application limit of linear notch mechanics in elastic-plastic solids is proposed, based on theoretical and FEM elastic-plastic analyses ; this limit corresponds to the condition of small-scale yielding in linear fracture mechanics. Moreover, tensile tests of notched plates in practical materials, which are advanced thermoplastics and their ...

Experimental verification of the virtual isotropic material concept for the last-ply-failure of U-notched quasi-isotropic E-glass/epoxy composite laminates under tension-shear loading

Journal of Industrial Textiles, 2022
Fracture investigation of U-notched E-glass/epoxy laminated composite specimens with various notch root radii is performed under mixed mode I/II loading conditions both experimentally and theoretically.

An anthropometric evaluation of the scapula, with emphasis on the coracoid process and glenoid fossa in a South African population

Heliyon, 2020
The exact dimensions of the scapula, including the coracoid process and glenoid fossa, are fundamental in the patho-mechanics of the glenohumeral joint (GHJ); as these structures act as initiators of shoulder movement.

Notch promotes neural lineage entry by pluripotent embryonic stem cells [PDF]

, 2006
A central challenge in embryonic stem (ES) cell biology is to understand how to impose direction on primary lineage commitment. In basal culture conditions, the majority of ES cells convert asynchronously into neural cells.

Effect of different surface conditions on fatigue properties of 7N01 aluminum alloy and the behavioral mechanism of crack of the alloy under alternating load

Materials Research Express, 2020
In this paper, the surface of 7N01 aluminum alloy profile is sandblasted or electropolished. The influence of different surface conditions on its conditional fatigue strength and fatigue mechanism under the alternating load after prefabricated short ...

Notch activates Wnt-4 signalling to control medio-lateral patterning of the pronephros [PDF]

, 2009
Previous studies have highlighted a role for the Notch signalling pathway during pronephrogenesis in the amphibian Xenopus laevis, and in nephron development in the mammalian metanephros, yet a mechanism for this function remains elusive.

Fatigue of Fillet-welded Joint Assessment by the FEA Simulation of Damage Accumulation [PDF]

Инженерно-строительный журнал, 2011
Fatigue strength evaluation of non-continuous incomplete penetration fillet-welded joints transferring stress flow by the S-N criteria incorporating the «Hot-spot stress» or «Notch-stress» approaches is dubious since the characteristic stress at the ...
