Delamination Crack

Abstract Mode I dynamic delamination fracture was studied with two polymeric fiber reinforced composites. Wedge insertion fracture test on a Kolsky bar (or split Hopkinson pressure bar) apparatus was conducted. A speed about 1,000 m/s of Mode I delamination crack propagation was achieved using high rates of loading. Dynamic fracture and crack propagation were modeled by the finite element method. Dynamic initiation fracture toughnesses of both composites S2/8552 and IM7/977-3 were obtained. For IM7/977-3, dynamic fracture toughness of IM7/977-3 associated with the high speed of propagating crack was examined. It is found that the dynamic fracture toughness of the delamination crack propagating at speed up to 1,000 m/s approximately equals to the dynamic initiation fracture toughness, which is again approximately equal to the static fracture toughness.
