    Abstract
  • A numerical calculation was carried out for the accelerated combined flyers by colliding explosive waves initiated by two symmetrical detonation initiators.In the calculation, Steinberg-Guinan (SG) strength model was used for the flyers to describe dynamic behaviors.From the calculation, the flying process and wave-propagating images were obtained.The results from our calculation are consistent with those from our actual measurements, demonstrating that the SG strength model is suitable for the combined flyers loaded with two head-on colliding explosive waves.This work lays a foundation for the study of suitability of the strength model at high strain rates and will serve as valuable reference for better understanding materials' constitutive relations and their dynamic behaviors in the colliding area.
