On impact perforation fracture in polymeric materials

Kobayashi Akira; Ogihara Shinji; Yamasaki Fumitomo; Ishigure Tomoyuki

Abstract:High velocity impact tests are conducted by launching spherical stainless steel and PMMA projectiles into thin PMMA plate targets at various velocities. Ballistic phase diagrams are obtained which indicate the fracture behavior in targets and projectiles. Quasi-static perforation tests are also performed. The fracture surfaces in targets are examined microscopically.

Key Words:fracture, impact, PMMA, projectile, sabot
