Аннотация
The problem of numerical simulation is solved for operators (tensors) of the stress and strain concentrations, which are related material-average stresses and strains with their local values in epoxyphenolic composites reinforced randomly by short polyimide fibers with antifrictional dispersed additives of polytetrafluoroethylene. Simulation is based on the generalized singular approximation of random field theory. The dependences of mentioned operators on the percentage of isotropic components are investigated. It is shown that an increase in the antifrictional additive concentration with a fixed fiber concentration does not result in a substantial decrease in the local elastic characteristics of the composite.
