Abstract
- This study investigated the similarity law of ultrasonic propagation in CFRP with concentrically curved fibers. The similarity law was formulated by introducing a new dimensionless number D. Additionally, the similarity law for a two-dimensionally propagating bulk wave was mathematically proven using the governing equation. A numerical simulation was conducted to visually demonstrate how this similarity law is held in CFRP with concentrically curved fibers. The simulation results revealed that the wavefronts of waves generated at different points had geometrically similar shapes when the D values for each wavefront were identical. The experimental visualization of ultrasonic propagation through a CFRP plate with concentrically curved fibers was also conducted, and the results revealed that the similarity law held in actual CFRP material specimens.
