| description |
The article experimentally and numerically investigates the effectiveness of low-frequency acoustic nondestructive evaluation (NDE) and the localization of possible delaminations in a multilayered carbon fiber reinforced plastic (CFRP) panel with transverse isotropy of the material. The experiments were carried out on a flat square panel, where wave motions were excited by a disk-shaped omnidirectional piezoelectric (PZT) actuator placed at the center of the 2 mm-thick panel and artificially created circular delaminations, with diameters of 1.5 and 3 cm, were located along the diagonals of the square at a distance of 22 cm from the center. The dispersion analysis of antisymmetric (A0) and symmetric (S0) Lamb waves and horizontally polarized shear waves (SH0) for such a panel, with given engineering constants, and subsequent finite element (FE) study showed that only A0 waves generated at sound frequencies can be used for delamination diagnostics by registering of out-of-plane velocities at surface points of the tested structure using a simple laser vibrometer. It is shown that due to sufficient sensitivity, noise immunity, and reliability, the proposed method of acoustic testing of thin-walled composite parts can be effectively used in production conditions. |
