Optical non destructive testing of composite materials - state of art

Holographic and moire non-destructive testing are well adapted for analysis of composite materials, namely for delamination, cracks inspection, buckling during loading mode and physico-chemical states, because they are quick, cheap and more powerful than other procedures. Some cautions in experimental processing, fringe control and interpretation are nevertheless important to respect particulary for automatic decision of reject or acceptation. © 1989, SPIE.SCOPUS: ar.j
