L\u2019un des enjeux en contr\u00f4le de sant\u00e9 des structures est la d\u00e9tection pr\u00e9coce de l\u2019endommagement avant que ce dernier ne conduise \u00e0 la ruine. Dans ce contexte, l\u2019\u00e9mission acoustique est une technique bien adapt\u00e9e afin de suivre, en temps r\u00e9el, l\u2019\u00e9tat de sant\u00e9 d\u2019une structure ou des mat\u00e9riaux qui la constituent. En effet, les m\u00e9canismes d\u2019endommagement s\u2019accompagnent de lib\u00e9ration d\u2019\u00e9nergie sous forme d\u2019ondes acoustiques. Des capteurs dispos\u00e9s \u00e0 la surface de structures ou d\u2019\u00e9prouvettes de laboratoire permettent d\u2019enregistrer les signaux d\u2019EA.<\/p>\n

Cet ouvrage est d\u00e9di\u00e9 \u00e0 l\u2019identification de la signature acoustique des diff\u00e9rents m\u00e9canismes d\u2019endommagement se produisant dans les mat\u00e9riaux composites \u00e0 matrice organique, mais aussi dans les mat\u00e9riaux composites \u00e0 matrice c\u00e9ramique. Les apports de cette approche sont pr\u00e9sent\u00e9s, ainsi que les principales difficult\u00e9s et les limites. Aussi, la pr\u00e9vision de la dur\u00e9e de vie \u00e0 l\u2019aide de l\u2019EA pour des essais de longues dur\u00e9es est discut\u00e9e.<\/p>\n","protected":false},"excerpt":{"rendered":"
