ANALYSIS OF POLYMETHYLMETHACRYLATE DESTRUCTION ON HIGH-SPEED LOADING

A system of equations is presented for describing the shock-compressed state of polymethylmethacrylate in the approximation of uniaxial deformation. With the use of the Prandtl–Reuss model, the mechanism of transition of the brittle failure of polymethylmethacrylate to the brittle-plastic one at high speeds of the striker and high times of its effect on this mechanism has been determined.
