“…where κ is the wavenumber, ω is the frequency, and Xðκ,ωÞ denotes the FKD. Based on equation (1), the data are directly mapped from the time-distance space into the frequency-wavenumber space. The ridges in the frequency-wavenumber represent the dispersion curves.…”

“…The composite laminates are widely used in many industries, 1 such as aerospace, energy, and civil engineering, because of their excellent mechanical properties 2 including high strength-to-weight ratio, high modulus-to-weight ratio, and fatigue resistances ability. However, the composite laminates may be put in safety risks due to undesired damages, such as delamination, impact damage, and matrix cracking.…”

“…Composite materials have attracted interest in the fields of aviation and aerospace due to their excellent specific strength and stiffness properties. Consequently, they progressively evolved into the primary structural material for the current generation of aircraft [1,2]. However, low-velocity impact or long-term loading can cause delamination, debonding, matrix cracking, and other structural damage faults [3].…”
