[crack] arrest lines Explanation: arrest lines is a recognised term in metal fatigue - see ref below. Other terms include beach marks, striation and ratcheting, but given the closeness of "arrest lines" to the source language term, it would seem to be the most reliable here. https://books.google.co.uk/books?id=B2aAPVa1TloC&pg=PA36&lpg... NB: this resource is 409 pages. Search "arrest lines" from within: https://www.google.co.uk/url?sa=t&rct=j&q=&esrc=s&source=web... |

Reference: Ligne d'arrët à la fin de la citation ! Reference information: deuxième stade : propagation de la fissure ; au moins une fissure atteint une taille critique et commence à se propager ; la propagation se fait dans un plan perpendiculaire à la sollicitation (mode d'ouverture I) ; la fissure progresse à chaque cycle, donc si l'on regarde le faciès de rupture au microscope électronique à balayage (MEB), on voit des stries de fatigue ; si la sollicitation change (arrêt et redémarrage de la machine, changement de régime), il se produit une ligne plus marquée, visible à l'œil nu, appelée ***ligne d'arrêt*** ; https://fr.wikipedia.org/wiki/Fatigue_%28mat%C3%A9riau%29 |

Reference: Crack arrest lines etc Reference information: This looks like a bit more detail on the ppt you were reading - if that helps - (striation, beach marks, ratcheting): https://www.google.fr/url?sa=t&rct=j&q=&esrc=s&source=web&cd... And - there is also interesting info, if you Google "crack arrest lines" which, given the source term, sounds potentially relevant... |
