Projectile Material Model Included Phase Transformation Erosion

Article Preview

Abstract:

High temperature generated by target impact causes projectile austenite phase transformation. At high temperature, the austenite strength decreases rapidly and undergoes phase transformation erosion because of target impact. On this basis, a projectile material model which took phase transformation erosion into consideration was established and then the model was verified. Model simulation showed that after phase transformation erosion the projectile was subjective to tensile and compression instability. Dual-arc head design would significantly reduce projectile penetration resistance and decrease phase transformation influence on projectile stability.
