Ballistic limit of shielding structures are an important field in the research of space shielding technology. Based on the theories of plates, the paper obtains the ballistic limit equation for dual-wall structures. The equation obtained is valid for dual-wall structures subjected to hypervelocity impacts by spherical projectiles. The Rayleigh-Ritz method and Tresca yielding criteria is used in the analysis. To verify the equation, predictions to experimental tests are presented. Analysis of the predictions and comparisons with existing ballistic limit equations are also presented. The ballistic limit curve agrees well with existing ones.
