详细

Body waves in an isotropic elastic space propagating along the line of action of a concentrated force singularity are analyzed. It is shown that along the line of action of the force singularity, in addition to the P-wave, the S-wave also propagates. The erroneous statements found in a number of publications about the absence of S-waves on the line of action of the force singularity are noted.
