Overview

Analysis reveals improved mechanical behavior modeling in polyethylene gas pipes, indicating significant aging impacts.

Key Points

  • The proposed rheological model shows a goodness of fit between 0.982 and 0.999 for tensile tests across aging times.
  • Findings emphasize the complex deformation behavior and aging effects in polyethylene gas pipes during long-term use.
  • This research utilizes continuum mechanics and aging tests to enhance the simulation fidelity of polyethylene's mechanical properties.
  • The model provides valuable insights for predicting service life and performance of aging polyethylene pipelines.
