Abstract

Procédé pour déterminer les tensions internes dans des éléments de construction mécanique ou de chaudronnerie. Après perçage de la rainure annulaire 7 jusqu'à la profondeur où la fonction d'amortissement n'est plus valable et mesure des variations de dilatation, on élimine le noyau 13 subsistant du point de mesure, puis on colle la jauge extensométrique 3 sur le nouveau point de mesure et on creuse une nouvelle rainure annulaire en mesurant les variations de dilatation, après quoi on répète ces opérations par phases successives jusqu'à ce qu'on ait atteint la profondeur de perçage prédéterminée, et, pour chaque nouveau noyau de point de mesure, on détermine une fonction d'amortissement séparée. Ce procédé est en particulier destiné à déterminer les tensions internes à de grandes profondeurs dans des éléments de construction mécanique ou de chaudronnerie
