摘要：

Field tests show that cracks can propagate steadily at more than 300 m sec** minus **1 along gas-pressurized pipelines of normally ductile polyethylene, once initiated by impact. In instrumented drop-weight testing of double torsion specimens, constant velocity brittle crack propagation is observed and since the static deformation mode remains admissible in the dynamic regime, a simple analysis is possible.
