Acoustic waves generated by a laser point pulse in a transversely isotropic cylinder

摘要: A three-dimensional (3D) model is presented to predict the acoustic waves generated by a laser point pulse in transversely isotropic cylinder. The Fourier series expansion and two-dimensional transform are introduced calculate 3D transient response under either ablation or thermoelastic generation. physical numerical inverse scheme applied fiber reinforced composite cylinder with strong anisotropy. Experimental radial displacements of surface detected ultrasonic technique analyzed ray trajectories for both generation regimes. Corresponding theoretical obtained numerically compared experimental signals. Good agreement found between results. focusing effects that anisotropy gives rise observed theory experiment regime.
