Oasys LS-DYNA Environment: User Guide (Version 8.1) LS-DYNA Manual Section: *CONTACT_ERODING_SURFACE_TO_SURFACE Example of: Projectile penetrates Plate Example Filename: projectile_plate.key Description: A projectile strikes a plate at a critical angle. Model: The hemispherical projectile has a length of 7.67 cm and a diameter of 0.767 cm. The plate measures 23.01 cm × 23 cm × 0.64 cm. The projectile and the plate are elastic perfectly plastic with failure strain. The initial velocity of the projectile is 0.129 cm/µsec at an angle of 75 degrees. The calculation terminates at 110.0 µsec. Input: All nodes have initial velocity cards (*INITIAL_VELOCITY) A type 14 eroding surface to surface with the bucket sorting algorithm contact represents the interface between the projectile material and the plate material (*CONTACT_ERODING_SURFACE_TO_SURFACE). Results: The projectile fractures into a tip and trailing portion. The trailing portion punches a hole through the plate while the tip reflects off the plate. Page A.33
