Description

Different analytical methods have been used to study the waves generated by transient sources of finite extent. Methods have included: high-frequency approximations, Fourier superposition, linear superposition of the fields from elementary sources, and finite difference and finite element methods. Bresse and Hutchins [1] reported an exact analytical solution to an axisymmetric source on an elastic half-space, which is more numerically efficient compared with the previous methods.
