Abstract
This paper is concerned with the dynamic response of a rigid strip of finite width bonded to the surface of a multilayered poroelastic half plane. The strip is subjected to time-harmonic vertical, horizontal and moment loadings. The half plane under consideration consists of a number of layers with different thickness and material properties. A discretization technique based on the rigid body displacement boundary conditions at the strip-half plane contact surface and dynamic Green’s functions of a multilayered poroelastic half plane is used to analyze the interaction problem. The discretization method used in this paper yields a flexibility equation system for determination of contact tractions at strip-half plane interface. Comparisons with existing studies for a rigid strip on a homogeneous medium are presented to establish the accuracy of the present scheme. Selected numerical results for impedances of a rigid strip on different poroelastic media are presented to portray the influence of poroelastic effects on the dynamic interaction problem.
