In part I of this analysis analytical expressions were derived for the elastic fields in a cross-anisotropic and isotropic half space with various loadings applied over a circular area on the surface. Two special cases are now analyzed. Consideration is first given to derive the analytical expressions for the elastic field along the z-axis perpendicular to the surface. Then the elastic field at the surface z = 0 is found. Finally, numerical results reveal the effect of concentric and eccentric loading on the vertical soil pressure and the maximum shear stress below the surface. It is found that the nature of the quadratic loading significantly effects the magnitude and distribution of the maximum shear stress. It is also shown that some types of cross-anisotropy may also give significantly different results than those for isotropic materials.
