Structures both for resisting impacts as well as delivering impacts are described. Generally, the impact resisting structures are formed with means for preventing the reinforcing intersection of a sonic wave train with its own reflection within the structure, such that at least one shock wave fracture mode is eliminated. More specifically, the structures are formed with means for suppressing the specular reflection of high frequency energy at one or more surfaces of the structure. This means may comprise irregularities formed in a surface to roughen the surface in a predetermined relationship with the wavelength of the sonic energy. The impact delivery structures are adapted to rapidly deliver kinetic energy after an initial contact with an object. These structures may comprise a projectiles having a jacket and a spline supported therein for providing a high velocity channel through which a sonic energy wave train may propagate. This is a division of U.S. patent application Ser. No. 695,411, filed Jan. 25, 1985, now patent No. 4,704,943, which is a continuation application of S.N. 273,965, filed June 15, 1981 now abandoned.

In a projectile for delivering an impact to an object, a central structure, comprising: ceramic spline means for providing a high velocity channel component through which a sonic energy wave train may propagate in response to a collision with said object; and jacket means for providing a higher density mass component which supports said spline means generally coaxially within said projectile, said jacket means being formed with buttress thread means for supporting said spline means.
