Abstract:

A comparison of fracture load given by conventional definition and acoustic emission is made for three cases: ?Fracture load at maximum load, ?Fracture load at "pop-in", ?Critical load defined by 5% offset procedure. Comparison has been made for three materials, Steel APX 52, Honeycomb core composite and 7000 T 73 aluminum alloy.In each case, good agreement is found between acoustic emission and conventional fracture load. Acoustic emission is a power full method to detect the critical event particularly when large plastic deformation occurs before ductile tearing.
