Axial Pullout Behavior of Buried Medium-Density Polyethylene Gas Distribution Pipes

This paper presents an experimental investigation into the axial pullout behavior of buried medium-density polyethylene (MDPE) pipes under various pulling rates. Tests were conducted in a facility developed at the Memorial University of Newfoundland. During the tests, pipe elongations and axial strains were measured to examine the mobilization of axial force with leading end displacement, and circumferential strains were measured to capture the...
