A numerical method based on integration along bicharacteristics is presented for analysing two-dimensional stress wave propagation problem in layered orthotropic plates. This method is an extension of the method proposed by Clifton isotropic plane problem. The numerical stability is discussed. The method is applied to simulate stress wave propagation in a semi-infinite plate composed of two different orthotropic materials.
