In conducting fatigue tests, several specimens are run at various loads or stress levels to determine the number of stress cycles to cause failure. These results are then plotted as a logarithmic or semi-logarithmic graph in which stress (S) is the ordinate and the number of cycles (N) the abscissa. The curves obtained are generally called S-N curves. Usually, the data are plotted on semi-logarithmic graphs in which the number of cycles is recorded on the logarithmic scale. 2, record 1, English, - S%2DN%20diagram

Although "diagram" and "curve" are not perfectly synonymous ("diagram" has a more abstract meaning than "curve"), in this case, the authors consulted do not distinguish between "S-N diagram" and "S-N curve". 5, record 1, English, - S%2DN%20diagram

La méthode classique pour déterminer la limite d'endurance d'un métal consiste à procéder à un certain nombre d'essais sous des charges différentes jusqu'à obtenir la rupture de chaque éprouvette; on construit une courbe, dite courbe de Wöhler, en portant, pour chaque éprouvette, en abscisse, avec une échelle logarithmique, le nombre de cycles qui ont amené la rupture et, en ordonnées, avec une échelle linéaire, la contrainte maximum produite au cours de chaque cycle; cette courbe admet, en général, une asymptote qui définit la limite d'endurance [...] 1, record 1, French, - courbe%20de%20W%C3%B6hler
