Abstract | In this study the far field shape functions in the three different model of
half spaces such as homogeneous half space a homogeneous full space and
two homogeneous half spaces bonded together for the case of two dimensional
a nd three dimensional problems are considered. The models are subjected to
various harmonic vibrations such as inplane axisymmetric , asymmetric and
antiplant axisymmetric , antisymmetric harmonic vibration for the case of two
dimensional problem. In the case of three dimensional problem, the vibration
cases considered are axisymmetric , asymmetric point load and pure torsion. For
radiating element the shape functions are derived as the combination of above
cases. It is found that the body wave solution can be separated into pressure
and shear waves with the oscillating circular functions whose periods of
oscillation are constant, which depends on underlying a nd overlying media
pressure and shear wave nondimensionalized numbers. To get the approximate
shape function in intermediate field, a calibration technique is suggested. |
