Application of dynamical ion mixing techniques to the improvement of the fatigue resistance of a 316l stainless steel... It has been shown that a significant improvement of the fatigue life is obtained by this way at 293 K and at 573 K due to a considerable modification of surface damage leading to an important delay for crack initiation
Effect of iron content on hot tearing of high-strength al-mg-si alloy... Furthermore, by comparing the fracture surfaces of the tensile testing sample and DC billet, the temperature range of crack initiation of the alloy was examined....
Synchrotron x-ray micro-diffraction – probing stress state in encapsulated thin silicon solar cells ... To further understand this phenomenon, the synchrotron X-ray micro-diffraction tool was used to perform stress measurements and mapping of the solar cells in the vicinity of the most typically observed crack initiation location, the solder joint....
amorce de fissure
industrie mécanique - techdico
Ces amorces de fissures permettent d'obtenir une séparation complète des lanières métalliques (1) au voisinage des éléments de jonction (3), tandis qu'aucune amorce de fissure ne se forme dans les nœuds de jonction (4).

This leads to the complete separation of the metal wires (1) in the region of the webs (3), while no incipient cracks form at the network nodes (4).

Traductions en contexte français - anglais

Au cours de la formation de la lame, la jonction est recuite afin d'éviter la formation d'un défaut ou d'une amorce de fissure le long de la jonction.

During formation of the blade the junction is annealed to avoid formation of a flaw or incipient fracture along the junction.
