Web1 Jan 2004 · The peak pressure for propagating shocks is given by P = 9Uu. (3.47) where p is the material's density; U, the shock velocity and u, the particle velocity. Because the pressure generated by shock wave propagation can exceed material strength by several orders of magnitude, we can view the early stages of materials response as hydrodynamic. Web15 Oct 2024 · The shock wave propagation presents an impedance, sensitive to porosity, but not to specific surface area. Such surprising phenomena are due to the similar sensitivities in density and stress variations to porosity or specific surface area.
