TLDR
Based on the dimensional analysis of concrete penetration by a non-deformable projectile and an analytical penetration model, two dimensionless numbers, i.e., the impact function I and the geometry function of projectile N are defined and used in a dimensionless formula to predict the penetration depth.About:

Local impact effects of hard missiles on concrete targets
TL;DR: In this paper, a collection of empirical formulae to predict the penetration depth, scabbing thickness and perforation thickness is presented in both Imperial and SI units and the current status of various design codes is summarized based on a dimensional analysis, dominant non-dimensional parameters that may influence the local impact effects on concrete targets are obtained and then used to present some of the test data Various nose shape factors are compared and a unique definition of the nose shape factor is suggested Analytical models and numerical simulation methods for penetration are summarized Criticisms are made for the current understanding of

An empirical equation for penetration depth of ogive-nose projectiles into concrete targets
TL;DR: Canfield and Clator as mentioned in this paper developed an empirical equation for penetration depth of ogive-nose projectiles penetrating concrete targets at normal impact, which contains a single, dimensionless empirical constant that depends only on the unconfined compressive strength of the target.

A review of procedures for the analysis and design of concrete structures to resist missile impact effects
TL;DR: In this paper, the effects of a hard impact on a concrete barrier wall are discussed. But this paper only deals with the effect of "hard" missile impact and does not deal with the impact on "soft" barrier walls.
