The bone fabric is exposed to destruction as a result of influence of a shock wave and waves of unloading following it, generating a with great dispatch-wave osteoporosis, according to electron-microscopic researches in the field of a gunshot wound, except direct traumatic the channel. The purpose of the given work is working out of mathematical model and a numerical design procedure of high-speed interaction of a metal splinter and a bone fabric. The mathematical models of deformation and destruction of a bone fabric in frameworks of mechanics of the continuous environment which considers viscous and fragile mechanisms of destruction of a bone fabric of various structures is offered. Numerical realization is carried out in full three-dimensional statement. Destruction processes in the biocomposites which are conditional analogues of tubular and lamellar bones are investigated, at blow by steel splinters of the various forms with a speed of 500 m/s.
