WebHydrostatic shock pressure (P) is obtained from the equation of state. Viscous stress (Q) is time-dependent, and for a structured shock wave, it can be written as [37], where ˜ is the coeﬃcient of shock viscosity. Exponent m on the strain rate term in Eq. (2 ) depends on coupling between strain rate and shock viscosity where m = 1 for a ... WebAnswer (1 of 4): Like a lot of other things…it depends. I’m going to assume that, by shockwave, you mean the “energy dump” and temporary cavitation of the round.
