The growth of impact damage in compressively loaded laminates


Chai, Herzl (1982) The growth of impact damage in compressively loaded laminates. Dissertation (Ph.D.), California Institute of Technology.


An experimental program to determine the phenomenological aspects of composite panel failure under simultaneous compressive in-plane loading and low-velocity transverse impact (0-250 ft/sec) was carried out. High-speed photography coupled with the shadow moire technique was used to record the failure propagation phenomenon. The information gained from these records, supplemented by plate sectioning and observation for interior damage, has provided information regarding the failure propagation mechanisms. The results show that the failure process can be divided into two phases. In the first phase the plate is impacted, and the resulting response causes interlaminar separation. In the second phase the local damage spreads to the undamaged portion of the plate through a combination of laminate buckling and further delamination.
