抄録	Wave motion in a layered plate, including loading regions, were fomulized using the semi-analytical finite element method (strip element method) and calculated at every frequency step, which resulted in the simulations of Lamb wave exitated by angled beam transducers in the time domain. These calculations required less computational time and memory than the conventional methods such as FEM and BEM. The numerical results were visualized and the snapshots of Lamb wave propagation revealed the some phenomena regarding S 0 mode exitation and stress distributions of S 0 and A 0 mode. The pure S 0 mode cannot be exited by angle beam transducers due to its long wavelength in a low frequency thickness range. The normal stress in the propagation direction in S 0 and A 0 mode and shear stress in S 0 mode abruptly varied with the position in the thickness direction in a crossply plate.
