| Abstract |
The paper presents outcomes of the study of short-timed shock action of the pulse electron
beam on the aluminum obstacle. Analysis of the generation of the stress wave near the loaded surface
based on the experimental data is provided. It is proved that wave generation in this case in contrast to
the action of laser beam takes place inside material in the area governed by the depth of electrons invasion. Relaxation of the stress wave starts from the boarder of this area. It was established that strongly
non-equilibrium processes are take place in this relaxation area causing dramatic change depending
on the shock parameters of the velocity of the stress and strength waves compared theirs stationary values. It is underlined that relaxation process has solo-wave nature in spite of the high stress amplitude.
Separation of the elastic and plastic stresses propagation takes place only after the end of relaxation process. |
