| Abstract: | This paper investigates the disturbance due to harmonic time dependence plane and line load in pre-stressed elastic half-space. A normal force has been considered to act on the surface of a semi-infinite elastic solid. Stresses and displacements due to the load are evaluated. The results obtained here are in agreement with the classical Lamb's problem in elastic wave propagation when the half-space is supposed to be initially stress-free. The numerical results include the stress distribution and the displacement at the surface; further, the results for stresses are shown graphically. |
