...B. A. Marcotte; I. R. Fleming High localized strain in geomembranes caused by indentations from coarse, uniform drainage aggregate is associated with long-term stress cracking and has been widely studied. A number of large-scale lab tests were carried out with direct measurement of the distribution...

...F.B. Abdelaal; R.K. Rowe; R.W.I. Brachman ABSTRACT: The susceptibility of a 1.5 mm thick high-density polyethylene geomembrane to brittle rupture from long-term stress cracking in a simulated municipal solid waste landfill liner is examined. The geomembrane was pre-aged in a leachate at 85°C...

..., geomembrane strain concentrations, geomembrane stress cracking pattern, geomembrane wrinkles, and geosynthetic resistance to differential settlement. The selected examples are such that the important behavioral aspect is not the behavior of the structure in which the geosynthetic is incorporated...

.... The predominant mode of premature failure of HDPE pipe and geomembrane is a quasi-brittle fracture initiated at stress concentrating surface notch geometries and/or unexpected point stresses. Such failures occur due to the fundamental stress cracking susceptibility of HDPE. The semi-crystalline, microstructure...

...J.P. Giroud Some high-density polyethylene geomembranes are more susceptible to stress cracking than others. When they are exposed to very low temperatures, these geomembranes may be shattered, i.e. they exhibit cracks (called shattering cracks) in many directions. This paper is devoted...
