    Body armor according to claim 1 wherein the projectile-resistant outer layer comprises Kevlar. Some exemplary superelastic products which use superelastic alloys are antennas, eyeglass frames and biomedical stents. Ammunition of this type will enable deer hunters to shoot without regard to intervening branches and brush and should greatly improve the percentage of quick kills and reduce the percentage of non-critical wounds that require hunters to spend many hours tracking wounded deer. After melting and flowing into place, the core material would be allowed to solidify in place. Metals and polymers differ, however, in that polymers are commonly viscoelastic and show hysteretic elastic effects. The invention and its many attendant objects and advantages will become better understood upon reading the description of the preferred embodiment in conjunction with the following drawings, wherein:. The limitations of known shotgun slugs are well known, including poor and inconsistent ballistic performance, low muzzle velocity, extremely short range, and wretched accuracy.

    Armor provides necessary protection for soldiers and it increases operational capability in environments where hostile fire is likely.One solution to this problem puts the back face of the ceramic strike plate in residual compression in order to increase the amount of load that the strike plate can withstand before failure begins.

    The Nitinol material is proposed as a surface material or coating for reinforcement or organic fiber fabrics and/or composites or aramid and UHMW polyethylene.The extreme hardness of the point 62 and the inertia of the slug 66 behind it will open a further path through the armor which the body 60 can follow and open further.

    Fully work-hardened Nitinol has a decent ,psi (MPa) tensile strength. That's not bad - better than any titanium alloy, and up there with common high.Conventional armor piercing ammunition has an embedded steel dart in the center of the bullet that continues forward after the jacket and lead around the dart have been stopped and dissipated against the armor.

    A ballistic armor uses shape memory alloys and novel joining techniques The invention utilizes shape memory alloys, also known as SMA, such as nitinol.The melting temperature of the Nitinol shell is much higher than most core materials, so the shell will be unaffected by the molten material in its hollow interior.

    Upon cooling, the metal shrinks more than the ceramic but is constrained by the bond between them so that the ceramic receives residual compressive stresses at its interfacing surface with the metal.
