May 02, 2020 · The effects of explosion point, interval time, trinitrotoluene (TNT) magnitude, pipe pressure, and the diameter-thickness ratio on the mechanical behavior of a steel pipe were investigated. Those results show that plastic deformation occurs and a dent appears on the right and upside wall of the steel pipe. Buckling Response Analysis of Buried Steel Pipe under The structural integrity of buried pipe is always threatened by explosive loads. To investigate the mechanical response of a buried steel pipe under multiple explosions, pipesoil interaction
Finite Element Analysis of the Mechan ical Behavior of Mitered Steel Pipe Elbows under Bending and Pressure Spyros A. Karamanos 1; Konstantinos Antoniou 2; Brent Keil 3; and Robert J. Card 4 1Univ. of Thessaly, Volos, Greece.E-mail:[email protected] Finite element analysis of high-density polyethylene pipe Aug 29, 2020 · In this paper, the mechanical behavior of HDPE pipe under various loads in pipe gallery was studied by finite element analysis (FEA). Stress concentrations were found at the fusion regions on inner surface of mitered elbows of HDPE pipe system.
The buried pipe crossing the subsidence area is prone to failure. The mechanical behavior of buried pipe in subsidence area was investigated in this paper. Mechanical behaviors and failure mechanisms of buried The study was conducted on the mechanical behaviors and failure mechanisms of buried PE pipes under fault movement, and the effects of gas pressure, fault dislocation, soil and pipe size on the mechanical behavior of PE pipes were discussed. The study indicates that gas pressure has a less effect on the mechanical behavior of PE pipe.
Aug 01, 2018 · Typical failure modes of buried polyethylene (PE) pipe include strength failure, buckling failure and excessive deformation [ 26 ]. Under mechanical excavation, large stress and deformation will occur in the PE pipe. Strength failure and excessive deformation will be the main failure modes for them. Seismic vulnerability assessment of buried pipelines:A 3D The mechanical behavior of the buried pipeline will be described considering the nonlinearity aspects of soil, in which an efficient nonlinear solver is proposed. These results are intended to guide and define the buried pipe networks towards more optimal design for the pipeline performance and its mechanical reliability. 2. Elasto-dynamic problem.
Plastic pipe reinforced by cross helically wound steel wires (PSP) is a new plastic-matrix steel composite pipe developed in China recently. To deeply understand the mechanical properties of buried PSPs, a finite element model of PSP subjected to non-axis symmetric load is proposed. The model is verified by replacing the parameters of PSP by those of steel pipe.

To account for the complex behavior of polyethylene pipe, laboratory tests were performed to study its thermal and mechanical properties. the 2D mechanical response of flexible buried Mechanical Analysis of Buried Polyethylene Pipelines under Jan 23, 2019 · The numerical simulation results indicated that the main failure form of buried PE pipe subjected to ground overload is ovalization deformation. With the increase in ground load, the ovalization deformation of the pipeline increases gradually and the maximum stress point of the pipe is transferred from the top (bottom) of the pipe to the midsection of the pipe.
