Abstract


Based on the experimental observations and analysis, the evolution mechanisms of mass loss process induced by plastic deformation and high temperature during penetration were proposed. A thermal dynamic mass loss model is proposed to investigate the mass loss based on the mechanisms of thermoplastic failure. Combining the temperature rise generated from the friction work and the plastic deformation work during the high-speed penetration process, the gradient distribution of the temperature change along the depth from the surface of a projectile is predicted. Through the comparison of the percentages of heat generated with different mechanisms at different locations of the projectile, the dominant mechanism of the mass loss between the friction and plastic deformation is analyzed to get an insight into the high-speed penetration process.
