Modeling of thermomechanical processes in woven composite material at blow by the striking element

摘要

The paper studies mechanical and thermomechanical interaction processes between striking element and multilayered woven barrier made of polymeric fabric. A simplified mathematical model is proposed. This model describes the inhibition of the damaging element due to energy dissipation, that is spent on irreversible strains of fabric threads stretching, friction during the mutual slippage of threads and barrier material heating. The defining equations parameters are estimated by identification according by the experimental data. The computational experiment results using the mathematical model can be used to diagnose armor protection according to the measurement of dynamic temperature fields.
