APPENDIX C
Degen Formula (1980)
Based on experimental investigations, Peter Degen (Reference 8) proposed a
partial revision to the Modified NDRC formula (Reference 4). The basic
penetration depth, x, computed by the Modified NDRC can be used to compute
the perforation thickness as follows:
tp

0.69
1.29

To prevent perforation, minimum concrete thickness, td, shall be
1.2 tp.
CRIEPI Formula (1985)
The Central Research Institute of the Electric Power Industry (CRIEPI) of Japan
(Reference 9) conducted impact testing focusing on low velocity missiles and proposed
the CRIEPI formula, which amended the Modified NDRC formula and the Chang formula
(Reference 3). Thus, the scabbing thickness (ts) and the perforation thickness (tp) are
given by:
C-12
