AbstractAbstract
[en] Advantages and difficulties of acoustic emission as a nondestructive testing technique are reviewed. It is shown that acoustic emission opens a new dimension in the study of material deformation and that much remains to be learnt in the field the theory of the source and the theory of acoustic wave propagation and detection

AbstractAbstract
[en] This study is concerned with the localization of acoustic emission sources. After a definition of the acoustic event, the electronic features are reviewed. Several solutions of the localization problem are examined: graphical, analytical or numerical methods. It appears that the square pattern formed by five sensors with a central sensor leads to the best precision on the largest area

Cette etude porte sur le probleme de localisation en surface des sources d'emission acoustique. Apres avoir expose ce qui caracterise l'evenement emission acoustique, on rappelle les caracteristiques electroniques des chaines de mesure. Plusieurs solutions au probleme de localisation d'une source sont proposees: methodes graphique, analytique ou numerique, qui montrent que le motif carre centre a cinq capteurs est la disposition qui conduit a la meilleure precision sur la plus grande surface exploree possibleOriginal Title

AbstractAbstract
[en] The acoustic emission testing of cracks is perturbed by mechanical parasites and by electrical parasites. Since these parasites are perfectly localized they can be eliminated by means of a localizer, if special adjustements are made and the apparatus is slightly modified
[fr]
La surveillance par detection d'emissions d'ondes de contraintes (EOC) de la propagation d'une fissure est perturbee d'une part, par des parasites mecaniques provenant de l'installation d'essai et d'autre part, par des parasites electriques. Ces parasites etant parfaitement localises, il est possible de les eliminer au moyen d'un localisateur, a condition d'effectuer des reglages particuliers et au prix d'une petite modification de l'appareilOriginal Title

AbstractAbstract
[en] The bibliography includes nearly all references in the literature on acoustic emission published during the three-year period, 1970 through 1972. Included in the 412 references are several for each of the associated technologies including: signature analysis, boiling detection, cavitation, leak detection, seismology, and rock mechanics. Information has also been obtained from eight abstracting and indexing services searched in compiling the bibliography. The bibliography has been arranged alphabetically by author and is cross referenced with a list of approximately 400 authors. Also included is a subject index. Technical articles listed were published in some 90 different journals and in 8 different languages. (U.S.)
