“…There are many methods to investigate the propagation characteristics of guided waves in composite laminates. These method include the Transfer matrix method (TMM) [3,4], the Global matrix method (GMM) [5], the scattering matrix method(SMM) [6], the stiffness transfer matrix method(STMM) [1], reverberation-ray matrix method(RMMM) [7,8], the finite element method (FEM) [9][10][11], and the semi-analysis finite element method (SAFE) [12]. Guided waves propagation can then be found by imposing appropriate boundary.…”
