ABSTRACT:
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.
