RISQuantitative Assessment of Damage in Buried Polyethylene Pipe Subjected to Land Subsidence
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Traditional investigation of polyethylene pipe (PE) subjected to external loads focused only on the study of mechanical behavior or the failure judgment, but could not predict the damage evolution process. In this paper, ...
Strength Analysis of Buried Polyethylene Pipeline Under Ground Subsidence Considering Multivariate Influence
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Due to the combined effects of natural and human factors, the ground subsidence is aggravated, which brings potential hazards to the normal operation of buried polyethylene (PE) pipelines. A variety of variables influences ...
Mechanical Behavior of Buried HDPE Pipe Subjected to Surface Load: Constitutive Modeling and Finite Element Method Simulations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the Sherwood–Frost constitutive model was first used to simulate the stress response and deformation process of buried high-density polyethylene (HDPE) pipe subjected to surface load, where parameters in ...
Defect Detection of Polyethylene Gas Pipeline Based on Convolutional Neural Networks and Image Processing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a method based on image recognition was proposed to detect the defects of polyethylene (PE) gas pipeline, especially the deformation due to the indentation. First, the pipeline -detection VGG (PD-VGG) model ...
