Detonation-driven fracture validation

Preliminary Validation

• Hydro-solver validation with fixed open slot [codes]
• Coupled solver validation for plastic flap opening [fluid codes] [solid codes]

Experiment

• J.E. Shepherd's external ASC webpage has several links to published experimental results
  • T.W. Chao, Gaseous detonation-driven fracture of tubes, PhD thesis, Caltech, 2004. (external PDF)
  • Elastic case (external webpage with data files)
  • Elastic case with inferometer meassurements (external webpage)
  • Fracturing case (external webpage)

Simulation

• Preliminary test calculations
  • Shock wave hitting a static thin cylinder (no shell solver)
  • AVI movie of tube fracture without fluid solver
• Elastic case (max pressure < 3.0MPa) [fluid codes] [solid codes]
  • PDF document by FehmiCirak on preliminary elastic computations performed without fluid solver
  • MPG movie of a normal shock propagating through elastic vibrating tube (uses signed distance)
  • Coupled simulation for thin shells
• Fracturing case (max pressure > 5.0MPa) [fluid codes] [solid codes]
  • Coupled simulation for thin fracturing shells
• Presentations
  • Towards simulation of detonation-induced shell dynamics with the Virtual Test Facility
    • Talk presented by RalfDeiterding at 3rd workshop for Computational Methods for Multidimensional flows, Jan 27-29, 2005, Heidelberg, Germany.
    • PowerPoint slides. The introduction on detonation simulation was an external PDF and not directly related to the fracturing tube experiment.
