1. A system for hardening and compacting a cylindrical structure, the system comprising:

  • a confinement assembly comprising;

    a cylindrical structure having a longitudinal axis;

    a glass sleeve surrounding and contacting the cylindrical structure; and

    a rigid outer shell encasing the glass sleeve and the cylindrical structure therewithin;

    a striker assembly comprising;

    a flat backing portion; and

    a protrusion portion extending from the flat backing portion;

    a launching mechanism for launching and directing the striker assembly in a direction substantially parallel to the longitudinal axis, to shatter the glass of the glass sleeve to create an explosive volume expansion of the glass, which due to the confinement assembly results in compressive forces being applied to the surface of the cylindrical structure, thereby hardening and compacting the cylindrical structure.
