Simulation Of Projectile Impact Using Continuum Damage Mechanics
Penetration and perforation of metallic targets by projectiles represent a longstanding area of research. Many authors have presented empirical relations based primarily on the diameter, mass and striking velocity of the projectile. The empirical equations are surveyed and assessed, and a historical background is presented to establish the origin of the initial equations used for impact scenarios. However, the main goal is to use Continuum Damage Mechanics in numerical simulation of projectile penetration and perforation. The simulations are validated by comparison with existing empirical equations, furnishing good agreement. Some consideration is given to the projectile, but the main focus remains on the target impact area. The historical equations are used for comparison and illustration only. Numerical simulations are performed using the non-linear dynamic impact code LS-DYNA (Hallquist, 1993). Use is made of a new constitutive model introduced into the code through the user interface, coupling viscoplasticity and damage. The new model uses a damage variable D to predict element failure during the penetration and perforation process.
