Keywords: composite laminates, interfacial damage, buckling, critical length
The size effect of interfacial failure and buckling in composite laminates under uniaxial compression are investigated. Six kinds of failure modes are governed by the length of composite laminates. The critical lengths of each region are estimated and a failure mode map based on relative stress-length/thickness relations is constructed.
