Numerical simulation on the evolution behavior of CFRP shell under high overloading condition
In face with the high-overloading service conditions of the key new material components in the future projectile weapons, the simulation models of Split Hopkinson Pressure Bar (SHPB) and carbon fiber reinforced polymer (CFRP) shell were established by the dynamic analysis software LS-DYNA, and then the dynamic numerical simulation on anti high-speed compression of CFRP shell was carried out.The failure behavior of the composite shell under high speed compression was described based on the failure criterion controlled by the progressive damage and the maximum strain.The numerical simulation results and the experiment results have better consistency by means of comparison and analysis.The calculated maximum stress of CFRP shell is 634MPa, the measured values is 602MPa(error is 5.4%), the shear failure near the roots of the reinforcing rings was the mainly failure mode, and the damage status of simulation result is well agreement with that of the experiment.
