High Velocity Impact of Glass-Reinforced Plastic Laminates with Sharp Nose Projectile Experimental Results Versus Some Models Predictions

摘要: This study investigates high velocity impact performance of glass-reinforced plastic (GRP) laminates struck by sharp nose conical projectiles and compares the experimental results with some available predicting models. Five models were selected for assessment. Close correlation was obtained between predicted ballistic limit velocities from models, which incorporated projectile geometry that results. Considerable scatter observed other Projectile deviation normal during perforation reason this discrepancy. Successful modification made to one using residual a test instead quasi-static
