Because of the limitation of the manufacturing technology, initial stress in functionally graded materials (FGM) and structures is inevitable.基于“增量变形力学”理论，研究了重力、厚度方向均匀初始应力和波传播方向非均匀初始应力下FGM板中导波的传播情况。 The Legendre polynomial series method is used to solve the coupled wave equations with variable coefficients. The convergence of the polynomial series method is discussed through the numerical examples.分别研究了初始应力对类兰姆波和SH波的影响，数值结果表明它们具有明显的差异。 The effect of the gravity on the wave propagation can be ignored.厚度方向的初始应力与波传播方向的初始应力对频散曲线以及位移和应力分布的影响有很大不同。
Because of the limitation of the manufacturing technology, initial stress in functionally graded materials (FGM) and structures is inevitable. Based on the theory of “Mechanics of Incremental Deformations”, the guided wave propagation in FGM plates under gravity, homogeneous initial stress in the thickness direction and inhomogeneous initial stress in the wave propagation direction is investigated. The Legendre polynomial series method is used to solve the coupled wave equations with variable coefficients. The convergence of the polynomial series method is discussed through the numerical examples. The effects of the initial stress on the Lamb-like wave and on the SH wave are investigated respectively and the numerical results show they are quite distinct. The effect of the gravity on the wave propagation can be ignored. The effects of the initial stress in the thickness direction are very different from those of the initial stress in the wave propagation direction, both on the dispersion curves and on the displacement and stress distributions.
