Title

Comment on the Reimerdes Ballistic Limit Equation for Dual-Wall Structural Systems

Abstract

The fundamental components of any micrometeoroid and orbital debris (MMOD) risk assessment are MMOD environment models, damage response predictor equations, and failure criteria. A damage response predictor equation, such as a ballistic limit equation (BLE), is developed to characterize the performance of a hypervelocity impact shield. Such an equation defines the threshold particle size that causes, for example, perforation or detached spall from the inner wall of a multiwall system as a function of velocity, impact angle, particle density, shield and inner-wall thicknesses, and particle shape. BLEs are typically drawn as lines of demarcation between regions of inner-wall failure and no failure in two-dimensional projectile-diameter—impact-velocity space.
