Impact characteristics of AlNi alloy projectile on single-layer target based on LS-DYNA secondary development
Based on the principle of plastic work temperature rise,the temperature term in Johnson Cook material model is simplified,and the chemical reaction mechanism of impact reaction materials is added.Based on the secondary development function under LS-DYNA platform,the constitutive model suitable for impact reaction materials is written.The simulation model of projectile impact on single-layer protective structure is established and the damage characteristics of ordinary materials and impact reaction materials are studied respectively.
