The Energy Absorption of Structural Target with Stiffeners Impacted by Projectile
Under penetrating condition, the plastic deformation of structural target is divided into local deformation region and global deformation region in this paper, calculate the energy absorbed by two deformations respectively and present a calculation method of energy absorption of structural target with stiffeners. Good agreement between the results of predicting the residual velocity of projectile by calculating the energy absorbed of structural target and results of numerical calculation illustrates that this method is reasonable.
