Delamination threshold loads for low velocity impact on composite laminates
G.A. Schoeppner,Serge Abrate +1 more
TL;DR: In this paper, the authors investigate the low velocity impact load level at which a composite laminate will delaminate and find that a sudden load drop occurs due to specimen stiffness loss as a result of laminate level damage.

Impact on composite structures
G. A. O. Davies,Robin Olsson +1 more
TL;DR: The problem of impact damage in laminated composite structures, and the consequent reduction in residual strength, has been a topic of continual research for over two decades as mentioned in this paper, and the number of journal papers on the subject now runs into four figures and most have been conscientiously reviewed by Abrate.

Impact resistance and damage characteristics of composite laminates
Tien-Wei Shyr,Yu-Hao Pan +1 more
TL;DR: In this paper, the authors investigated the damage characteristics and failure strengths of composite laminates at low velocity impact tests. And they found that when the impact energy increased over the threshold energy of the major damage, matrix cracking, delamination, and fiber breakage were observed at the back surface.

A Model for Predicting Damage in Graphite/Epoxy Laminated Composites Resulting from Low-Velocity Point Impact
Hyung Yun Choi,Fu-Kuo Chang +1 more
TL;DR: In this article, the impact damage of graphite/epoxy laminated composites caused by a low-velocity foreign object was investigated in terms of matrix cracking and delaminations resulting from a point-nose impac tor was the primary concern.
