A perturbation-based model for the prediction of responses involving delamination during small mass impacts on orthotropic composite plates

An analytical model was developed for the prediction of small-mass-impact response including delamination effects in orthotropic composite plates, which mainly focuses on the relatively weak resistance of fiber reinforced polymer (FRP) laminates to small mass impact. Mode parameters of the delaminated structure obtained through perturbation-based dynamic analysis were substituted into the dynamic impact model. The alterations of the structural...
