The influence of pressure parameters in a discharge filament generated by a high-voltage electric discharge in water on the drop of residual stresses is examined in this work. It is demonstrated that the level of the drop of residual stresses is determined by the pressure pulse value. A design procedure of pressure pulse parameters in a discharge filament is given. An experimental estimation of the effect of pressure amplitude in a discharge filament on the drop of tensile residual stresses in metal models is car- ried out. It is determined that the efficiency of the drop of residual stresses is mainly defined by the value of pressure pulse and practically does not depend on the maximum pressure in a discharge fila- ment.
