Abstract: The article deals with measurement of velocities of detonation in special
charges constructed with an inner channel. The detonation course of these charges
was investigated by measuring the velocities of detonation. The abnormalities
found in the detonation course were interpreted as a consequence of the channel
effect. For better understanding of the problem, the operation of channel effect
was also investigated by means of a numerical simulation using the method of
finite elements in the system ANSYS/LS DYNA3D.
