A new 1-D integral representation for dynamic response of anisotropic elastic solids due to a point force.

A new 1-D integral is presented for calculating the transient response due to a suddenly applied point force in a general anisotropic solid. The integral is based on a 2-D solution for a line force. It is shown that the integral reduces to a simple expression for the static Green's function immediately after the passage of the last bulk wave. The computational efficiency and accuracy of the proposed formulation are demonstrated by numerical examples for zinc and copper.
