Ply Thickness’ Effect on Composite Laminate under Low-Velocity Impact
Abstract:
Based on the two-dimensional Hashin failure criteria and the introduction of material degradation damage factor, low-speed impact model of composite laminated plate was established by ABAQUS with fiber and matrix’s failure modes being taken into consideration. The mode is verified by referring to Karakuzu test. Next, it analyzes single ply thickness’ effect on laminated plate’s response and damaged under low-velocity impact. The result shows that with the thickness increasing, impact contact time and laminated plate impact point’s deflection displacement reduce, while the impact force and volatile shocks are more obvious.
