Abstract

Relevance and goals. The appearance at the present time of a wide range of new high-strength synthetic fibers creates the prerequisites for a qualitative leap in the development of personal protective equipment with elements of discrete-fabric armor. Computer modeling of the functioning processes allows to shorten the duration of the design process and ensure a higher efficiency of personal protective equipment. The aim of the work is to determine the hierarchical structure of material models intended to describe the resistance to deformation and destruction of discrete-fabric elements of personal protective equipment under shock loading.
Materials and methods. As the researched materials of discrete-fabric elements of the means of individual protection produced by the domestic industry were chosen. When studying the influence of the structure of tissues on their resistance to deformation
and fracture, a theoretical-experimental method was used, based on the use of mathematical models of materials that take into account the fine structure of composite materials, fabrics and threads.
Results. A brief description of the hierarchical structure of mathematical models of materials of discrete-tissue elements of personal protective equipment is given, examples are a sequence of determining the parameters of these models, a comparison
of the results of computer simulation and experimental studies of the process of functioning of the armor.
Conclusions. Comparison of the results of computer simulation with the results of experiments showed that the proposed mathematical models of materials can be used in the design of personal protective equipment with elements of discrete-fabric armor. 

Key words
