Аннотация:This work proposes a model of hardening of an orthotropic material, which depends on strain rate. In contrast to kinematic hardening models containing an explicit dependence of stresses on deformations and strain rates, the proposed constitutive relations are presented in the form of a relationship between stresses, material damage accumulation parameters, and their variation rates. The model parameters can be determined experimentally using the method of the Hopkinson — Kolsky bar under dynamic tensile, compression, and shear loading in the plane of the composite layer. The model is numerically implemented using the Abaqus finite element modeling software. The simulation of an impact on the end of tubular specimens based on carbon fiber and polymer binder with layers stacked at different angles is carried out to estimate the specific absorption energy and select the optimal stacking of a multilayer polymer composite material.
