A numerical approach, based on the finite-element method was established in this paper to
simulate impact behavior of buried gas pipeline. A three-dimensional elastic perfectly plastic …

Long-distance natural gas transmission pipelines are planned to pass through the mountain
area of midwest China, portions of which are threatened by severe landslide hazards …

To avoid the in-service crack growth of pipelines, a fundamentally based mathematical
model of a partially debonded pipeline embedded in the rock mass is proposed, and the …
