TNO – BASF Ludwigshafen

The mechanical response of process piping loaded by an internal moving gas detonation has been investigated by DTRL, supporting the TNO Flow and Structural Dynamics section in a research project with BASF Ludwigshafen. Combined analytical and numerical methods have been explored in order to gain insight in the dynamic pipe response at high strain rate loading and elastic-plastic deformation. Special attention has been paid to the influence of:

  • Detonation (critical) velocity
  • Material properties
  • Limited plasticity and strain rate effects
  • Pipe bends, dead ends & T-sections
  • Pipe corrosion & assymetric loading
  • Detonation decay time
  • Mode coupling
  • Reflected flexural waves

Used Methods/Software:

  • Matcad / Maple / LS-Dyna
  • Analytical & numerical modelling
  • Comparison with experiments

Results have been published in:
