The development of instantaneous cavities in muscle tissue during high-velocity projectiles was analyzed and calculated. By simplifying the muscle tissue into an incompressible Voigt Kelvin viscoelastic fluid model, under the assumption of spherical symmetry and pure radial motion , A theoretical model for calculating the development of instantaneous cavity is established by using the basic equations of non-Newtonian fluid mechanics. The model can well reflect the fluctuation development of instantaneous cavity in muscle tissue and the change of pressure in the instantaneous cavity. And the experimental results are basically the same; through the theoretical model, you can quantitative theoretical analysis and study of instantaneous cavity.
