Abstract: The influence of controlled perturbations on the buckling of conical liners during their explosive compression is under study. In this case, there is folding on the inner surface of the liners, oriented along the generatrix of the cone. It is revealed that, as the Reynolds number increases, so does the number of fold, while the geometric dimensions of experimental devices remain the same. It is shown that scratching on the inner surface of the cladding makes it possible to control its buckling process.

Keywords: charge shaping process, liner buckling, controlled perturbations.
