摘要: An acoustic emission based investigation was conducted of damage initiation and progression in cellular foam core sandwich composites. Acoustic characteristics Mode I II fracture PVC were determined Single Edge Notch Bend End Flexure tests. Core shear growth successfully detected four point bending fatigue Analysis the signals confirmed that majority occurs at peak load levels increase can be correlated with reduction stiffness due to damage.
