Research Progress on Interlaminar Failure Behavior of Fiber Metal Laminates

Table 2

Common factors causing delamination damage of FMLs.

Origin	Common types
Manufacturing process	Residual stress during manufacturing; Machining (such as drilling); Hot and humid environment; Low-velocity impact; Out-of-plane load
Material and structural discontinuity in the design	Free edges; Openings; The skin-web connection position; Structural corners; Sudden changes in layer thickness; Switching position of solid material/sandwich material
