Underground main pipeline behaviour under a travelling impulse in the form of a triangle [PDF]
E3S Web of Conferences, 2021 The article presents an analysis of the dynamic response of an underground main pipeline under the action of a longitudinal wave, propagating in soil along the pipe. It is assumed that the elastic pipe has a finite length.
