The Collapse Mechanics of Polymer and Composite Liners

 

Rehabilitation

Plastic Pipes Conference Association # 2001 Munich

Gibson, Wu, Frost, Korsunsky

This paper considers the collapse of liners confined within rigid pipes and recommends design equations top avoid this effect. Two and three-dimensional aspects of the problem are examined. The onset of unstable collapse is well-described by the critical pressure predicted from analytical models and is essentially an elastic phenomenon.

Analysis of polyethylene (PE) pipes ductile failure (ballooning) suggests that it is directly related to the delayed necking phenomena and time to ductile failure of PE pipe can be evaluated as the time to delayed necking. The necking in polyethylene (PE) is studied under displacement control (ramp test) and load...
