摘要
Shear plugging and perforation of ductile circular plates struck by a blunt rigid projectile is studied in the present paper. Effects of transverse shear, bending and membrane deformations on the perforation process are included in a rigid-plastic analysis while the local indentation/penetration is estimated using the dynamic cavity expansion model. Analytical formulae for the perforation ballistic limit and the residual velocity are obtained for a range of plate thickness, which agree with the available experimental results on the perforation of metallic plates.
