Surface Displacement Field of a Coated Elastic Half-Space Under the Influence of a Moving Distributional Load
Öz
An analysis of the
distributed moving load along the surface of a coated half space is presented.
The formulation of the problem depends on the hyperbolic-elliptic asymptotic
model developed earlier by the authors. The integral solution of the
longitudinal and transverse displacements along the surface for the sub and
super-Rayleigh cases are obtained by using the uniform stationary phase method.
Numerical comparisons of the exact and asymptotic solutions of the longitudinal
displacement are illustrated for the certain cross-sections of the profile.
