High-Velocity Impact Behaviour of Prestressed Composite Plates under Bird Strike Loading

Figure 4

Increasing damage with increasing impact velocity visualised by ultrasonic C-scans of specimens with tensile preload (no delaminations but only matrix cracking).

(a) 97 m/s, 142 J

(b) 142 m/s, 311 J

(c) 171 m/s, 443 J
