A general non-homogeneous shear beam model is developed to account for any possible situation such as variat ions of soil density and shear modulus with depth and irregular cross-section of embankments. Closed-form analytical expressions are derived for natural frequencies, modal displacements, participation factors and others for all cases. In this approach, the average shear modulus across the width of embankments is expressed as a sectional power function of depth. Numerical results are presented in a graphical...

A general non-homogeneous shear beam model is developed to account for any possible situation such as variat ions of soil density and shear modulus with depth and irregular cross-section of embankments. Closed-form analytical expressions are derived for natural frequencies, modal displacements, participation factors and others for all cases. In this approach, the average shear modulus across the width of embankments is expressed as a sectional power function of depth. Numerical results are presented in a graphical form through a set of non-dimensional parameters. The effects of several factors associated with non- homogeneities both in material properties and in geometric shape on vibration characteristics of layered embankments are discussed. Some conclusions drawn here may be of pratical significance.

A numerical technique is given for obtaining the solution for the propagation of torsional waves in an elastic/viscoplastic cylinder subjected to a dynamically applied shear stress with non-linear radial variation at its end surface. The equations governing the dynamic torsional deformation of the cylinder are solved by means of the method of numerical integration along bicharacteristics. The numerical solutions for the torsional elastic waves in the cylinder are shown to be in close agreement with the existing exact solutions. The stability and convergence of the present technique are investigated by examining the error in the total energy of the numerical solution as time increases. The advantages and limitations of the present technique are discussed.
