The crystallographic characteristics of fracture in magnesium …

Fracture in a twin (parting) was observed as the primary mode of failure. In the temperature range 25–286°C, fractures occurred primarily in {303̄4} twins, while at −190°C the habit plane of …

Advanced beam model for fiber-bridging in unidirectional …

Later Yan et al. [9] introduced a numerical model based on an elastic-plastic damage interface between the adjacent plies of the composite laminate. The experiments by …

About the Nature of Quasi-Cleavage in Low-Carbon Steel

Analysis of the fracture surfaces has shown the presence of several "fish eye" flaws in the form of round regions on the fracture surface a with faceted quasi-cleavage morphology …

Strength and fracture of single-crystalline Ni3(Al,Ti) and Ni3(Al,Ta

La limite élastique et le taux d'écrouissage augmentent régulièrement quand on passe de Ni 75 Al 20 Ti 5 á Ni 75 Al 20 Ti 10 et á Ni 75 Al 20 Ti 5, ce dont rendent bien …

Micro-fracture behaviour induced by M-A constituent (Island …

On a identifi6 ce m6canisme de rupture par des essais COD et par des essais de r6silience de Charpy et l'on a trouv6 que le facteur qui contr61ait la fissuration par clivage 6tait …

social cleavage / fracture

"La fracture sociale" is a very special expression in France. It has been used a lot during 1995 presidential elections, to emphasize the fact that there is a growing gap between …

Crack tip parameters for large scale yielding and low constraint

The analysis is used to extend fracture mechanics concepts beyond the normal limits of J-integral theory. A simple correction for crack tip stresses is derived from the quasi-deformation …

Fracture décomposée en plans de clivage parallèles aux cylindres

Download scientific diagram | Fracture décomposée en plans de clivage parallèles aux cylindres. [Fracture split into cleavage planes parallel to the cylinders.] from publication: Phases ...

An analytical solution for double cantilever beam based on elastic

To overcome this deflection, Moura et al. [4], [5] developed a data reduction scheme based on beam theory and the concept of equivalent crack length, which allows the …

Three-dimensional fracture pattern analysis of the Obwegeser …

Only one of the observed split fractures (0.5%) followed exactly the fracture line described by Obwegeser and Dal Pont, whereas 40% followed the fracture line according to the Hunsuck …

Fracture mechanism maps in stress space

On peut construire, dans l'espace des contraintes, des diagrammes qui représentent la compétition entre les différents mécanismes conduisant à la rupture dans les …
