Ultrasonic wave characteristics in filament wound composite pipes
摘要
Abstract
The fiber undulation in filament wound composite pipes(FWCP)altered structural mechanical properties,thereby affecting ultrasonic guided wave propagation characteristics,which limited the application of ultrasonic guided wave non-destructive testing technology.In view of the above problems,meso-scale modeling of fiber undulation regions and equivalent stiffness calculation methods were proposed,combining the finite element eigenvalue frequency method with Floquet periodic boundary conditions,and establishing a guided wave finite element model for FWCP.The effects of fiber undulation on guided wave propagation characteristics were systematically investigated.The results demonstrate that fiber undulation reduces the overall stiffness of FWCP,leading to decreased phase velocity of ultrasonic guided waves while maintaining unchanged modal properties.Furthermore,the winding angle has a relatively small influence on the guided wave structure and does not cause changes in the modal properties of the guided wave.The research provides theoretical support for ultrasonic non-destructive testing in FWCP.关键词
