Abstract :
The C-scanning acoustic microscope (C-SAM) makes visible the matrix microcracks and delaminations in each layer of the composite laminates and provides a unique method for quantifying load damage in composites. Previous work on low-velocity impact study suggested that the damage, measured in the total area of delamination among various layers, was proportional to the energy. The authors conclude that the damage is proportional to the load in the extreme quasi-static case
