Document Introduction

This report systematically elaborates on the physical action principles and damage effect assessment methods for various types of conventional weapon munitions (fragmentation, shaped charge, high explosive, penetration). The report aims to fill the gap in existing literature regarding systematic and modernized discourse on the damage effects of weapon munitions. Its content synthesizes the author's teaching experience at several top technical universities in Russia and related scientific research achievements, providing an authoritative theoretical framework and practical analytical tools for students, researchers, and professionals in related fields.

The core of the report begins with a clear distinction between the concepts of damage effect and combat effectiveness. The former focuses on the damage capability of a munition when all its components function normally upon approaching the target, while the latter is a broader category that also includes factors such as delivery accuracy, component reliability, and countermeasures against enemy defenses. Building on this foundation, the report constructs generalized damage characteristics, such as the conditional damage law for contact-action munitions (e.g., armor-piercing projectiles) and the coordinate damage law for remote-action munitions (e.g., fragmentation shells, high-explosive shells). It also details the analysis of target damage levels (Class A, B, C), firing errors (systematic error, random error, grouping error), and different effectiveness evaluation models for single targets, clustered targets, and area targets.

The main body of the report delves into four major categories of munitions in separate thematic sections. Regarding fragmentation munitions, the content covers their classification, the formation mechanisms of natural and preformed fragments, statistical models of fragment fields (Weibull distribution, Mott's law), fragment external ballistics, and methods for calculating damage laws and optimizing munition parameters based on target vulnerability characteristics. Regarding shaped charge munitions, starting from the basic principles of the shaped charge phenomenon, the report discusses in detail the hydrodynamic theory of jet formation (PER theory), the explosive loading and collapse process of the liner, the penetration mechanism of the jet into the target, and analyzes the influence of design parameters, manufacturing processes, and operational conditions (such as standoff distance, rotation) on the penetration effect. Regarding high explosive munitions, the focus is on the parameter calculation of airblast, underwater, and underground explosion shockwaves, damage criteria for structures and personnel, and the explosion characteristics of Fuel-Air Explosives (FAE). Regarding penetration munitions, the interaction mechanisms between kinetic energy projectiles and targets, the mathematical formulation of penetration problems, and the specifics of high-velocity impact are explored.

Given that the study of explosion and impact processes is inseparable from the widespread application of numerical simulation, the report includes a dedicated chapter introducing the fundamentals of numerical simulation for high-speed processes. This includes the governing equations of continuum mechanics, constitutive models of materials under intense dynamic loads (elastic, hydrodynamic, elastic-plastic, etc.), and the selection principles for solvers in mainstream simulation software (e.g., ANSYS AUTODYN). Specific case studies are used to demonstrate the application process of numerical simulation. The report appendix provides practical information such as unit conversion tables.

This report does not cover the design and operation of weapon guidance and control systems. Its discussion is closely integrated with engineering practice, and the formulas and criteria used can be directly applied to estimate damage field parameters, analyze target vulnerability, determine safety distances, and evaluate the resistance of protective structures. It holds significant reference value for professionals engaged in damage effect research, explosion safety, counter-terrorism protection, and military equipment development.
