Abstract
Semianalytical formulas are developed to predict scabbing and perforation thicknesses for reinforced concrete panels subjected to impacts by solid steel missiles. The scabbing thickness is defined as the thickness that is just enough to prevent the peeling off of the back face of the panel opposite to the face of impact; perforation thickness is defined as the thickness that is just enough to allow a missile to pass through the panel without exit velocity. In the development of these formulas, simplified models for scabbing and for perforation were assumed; engineering mechanics principles were applied in the formulation, and the Bayesian statistics were utilized to determine coefficients in these formulas. The Bayesian approach was used because it can handle the estimation of parameters better than the classicial statistical method when suitable data are limited, as is presently the case in low velocity missile impact on concrete panels.
