Improvement of low-velocity impact and compression-after-impact performance by z-fibre pinning (2006, background): “Several studies have shown that delamination damage is initiated when the impact force reaches a critical value [12-15].”
Damage and failure in low energy impact of fiber-reinforced polymeric composite laminates (2012, background): “Schoeppner and Abrate [30] called this point as the ‘‘damage threshold load’’ (DTL); it equals the impact load at which there is sufficient accumulation of damage in the composite plate causing a noticeable reduction in its stiffness and hence a change in the slope in the contact force time history ”
Impact damage on fibre-reinforced polymer matrix composite – A review (2014, result): “However, some results showed that the delamination threshold load varied with the laminate thickness to the 3/2 power.(90,97) Fibre failure occurs under the impactor due to locally high stresses and indentation effects.”
Effects of ply clustering in laminated composite plates under low-velocity impact loading (2011, background): “In addition, experimental data and finite element simulations indicate that the delamination threshold load is independent of the boundary conditions and of the in-plane size of the plate [24, 25, 36].”
Impact on composite structures (2004, methodology): “2, as demonstrated by extensive experimental data presented by Schoeppner and Abrate(2000) and Cartié and Irving(2002).”
