Buckling of HDPE Liners

Application ID: 115341


In this example, the Bergstrom–Bischoff material model is used to model the temperature and strain dependent behavior of High Density Polyethylene (HDPE) used, for example, to make liners for damaged pipes in oil and gas applications, or to make type IV hydrogen storage vessels for fuel cells.

In both cases, the liner is prone to collapse due to penetration of gas between the liner and the hosting structure. This model predicts the collapse pressure for different working temperatures.
