Lamb waves in multilayered media: 3D and 6D formalisms

click here A mathematical model for analyzing Lamb waves propagating in stratified media with arbitrary elastic anisotropy is worked out.The model incorporates a combined Fundamental Matrix (FM) and Modified Transfer read more Matrix (MTM) methods.Multilayered unbounded plates with different types of boundary conditions imposed on the outer surfaces are considered.Closed form fundamental matrices and secular equations for dispersion relations are derived.
