Failure analysis of CFRP laminates subjected to compression after impact: FE simulation using discrete interface elements (2013, background): “This damage is particularly dangerous because it drastically reduces the residual mechanical characteristics of the structure, and, at the same time, can leave a very small visible mark on the impacted surface [1], which makes it difficult to detect.”

Determination of impact location on composite stiffened panels (2012, background): “The latter can be categorized as large mass impacts for which the impact time is long enough that the behaviour of the structure is similar to its response under quasi-static loading and local effects such as indentation are small (Davies and Olsson 2004).”
Failure mechanisms and damage evolution of laminated composites under compression after impact (CAI): Experimental and numerical study (2018, background): “As the delamination area increases and surpasses a critical size as a result of increasing impact energy, the CAI strength drops significantly and then tends to level off, where it is equivalent to a complete perforation of the same size as the delaminated region [12,20,21].”
Numerical simulation of impact tests on GFRP composite laminates (2011, background): “Although these materials offer very attractive properties, their application is often restricted by their vulnerability to transverse impact [1], forcing the adoption of large safety factors and resulting in significantly over-designed structures.”
