- Abstract
- The article describes mechanical and thermomechanical processes of interaction of damaging element with a multilayer barrier of polymer fabric. It is proposed to take into account the difference in conditions of energy absorption in different fabric layers on the basis of an approximate simulation of wave interaction of damaging element with the multilayer material at the initial stage of collision. The rates and displacements of damaging element and woven material found in this case (emporter movement of the package as a whole and relative slippage of the threads in fabric layers) are used as initial conditions for further calculation of the motion of a layered flexible barrier and determination of the work of stresses and friction forces on irreversible deformations. The developed improved model of thermomechanical processes in a woven barrier at collision with a striking element allows taking into account the difference in the conditions of energy absorption in the layers located at different distances from the front surface of the barrier. The results obtained give the possibility of improving the design of multi-layered woven armor from the point of view of ensuring maximum energy absorption upon impact damaging element.
