A multiscale model for the prediction of ballistic performance of fiber-reinforced composites

This study investigates in-depth the effects of dimensions and properties of constituents at microscale on the impact performance of macroscopic fiber-reinforced laminates. A numerical algorithm incorporating the dynamic shear-lag model is developed. Applying the numerical dynamic shear-lag model to three typical impulse forms, a common linear relationship between the optimal dimensionless viscosity and impulse duration emerges. This linear...
