An investigation was performed to study the effect of stacking sequence, thickness, and impactor's mass on the impact damage of graphite/epoxy laminated composites due to low-velocity impact. The major focus of the study was concentrated on the initial damage and the corresponding impact energy with respect to these parameters. Experiments were performed using specially designed line-nose impactors by which the resulting impact damage and failure mode of the composites could ...
An investigation was performed to study the impact damage of graphite/epoxy laminated composites caused by a low-velocity foreign object. The impact damage in terms of matrix cracking and delaminations resulting from a point-nose impactor was the primary concern. A model was developed for predicting the initiation of the damage and the extent of the final damage as a function of material properties, laminate configuration and the impactor's mass. The model ...
Impact damage in laminated composites caused by low-velocity impact was studied. The objective was to fundamentally understand the failure mechanisms and mechanics of fiber-reinforced composites resulting from impact and to identify the essential parameters governing the impact damage. Matrix cracks and delaminations were the primary concern of the study. A line-nosed impactor was adopted which could produce a uniformly distributed, transient dynamic load across the specimen's width. Accordingly, the impact ...
