Urban Damage and Airblast Technical Support

Problem Statement and Objectives

ERDC needed ARA to evaluate detailed normal stress patterns acting on
projectile noses during penetration/punching of thin slabs, with nose footprint contours cast in mathematical form (referred to as forcing function).

  • model projectile / thin-slab interactions

  • analyze contacting detonation and breach

  • partitioning of embedded detonation and energy

Results and Benefits

In cooperation with ERDC engines, the forcing function was implemented into PENCRV3D (a rigid body penetration code) and benchmarked against available penetration test results.
