Dynamic Response of Crossanisotropic Layered Media with Imperfect Interface under Axisymmetric Loads

Considering the incomplete contact between adjacent layers of crossanisotropic multilayered half-space media, an algorithm was derived based on spectral element method (SEM) to determine dynamic response at any point medium when axisymmetric harmonic load is applied. The used two equivalent parameters simulate relationship discontinuity displacement and stress. SEM employed for summation in integral calculation avoid infinite transformation greatly improve efficiency solution layered medium. accuracy developed verified by numerical examples as well method. Finally, extensive parametric analysis interface medium, namely, application external load, excitation frequency, heterogeneous properties conducted, providing a reliable basis engineering practice.
