Abstract
The Green’s function is employed to find the elastic radiation in an infinite homogeneous medium generated by several different sources. These sources all have a cylindrical shape and are finite in length, but are otherwise rather distinct. They include an expanding cylinder, an explosion in a borehole, and a cylinder under torsion. It is found that in principle, an explosion in a cylindrical hole creates both shear and compressional waves. The radiation from one surface‐mounted source is also found. This is a source (the Dynagoose) in which tension is maintained between a surface plate and a long cylinder wedged in a hole.
