Vibration and Snapthrough of Fluid-Conveying Graphene-Reinforced Composite Pipes Under Low-Velocity Impact

What is it about?

There exists a complex fluid structure coupling vibration in the aircraft, which affects the normal operation of the equipment. The flow of internal fluid will change the rigidity of the pipe and further affect the dynamic performance of the structure. The contact dynamic response of functionally graded composite pipe under low velocity impact is studied for the first time. It finds that although the fluid flow has little effects on the contact force, it greatly affects the vibration behaviours of the pipe. By providing this text, the sensitive parameters of contact force and dynamic response is obtained. The dual effects of material gradient distribution on the contact dynamic responses are revealed. These results will be helpful to the design of impact resistance of pipe.
