The results show that there exist attenuation in all propagation modes along viscoelastic cylindrical tube, and higher-order propagation modes haven't cut-off frequency.
The finite attenuation distance of the cylindrical and spherical detonation was deduced through analyzing the asymptotic attenuation.

Applying reiterative method, this Paper simulates the blasting stress field of cylindrical charge, and then, gets attenuation law stress peak value and characteristics of stress distribution.
