Yield of scratched geomembranes
Abstract In this paper, it is demonstrated that geomembranes that have a stress-strain curve with a yield peak, such as high-density polyethylene (HDPE) geomembranes, yield at a tensile strain that is significantly influenced by scratches on the surface of the geomembrane. It is shown that scratched HDPE geomebranes can exhibit yield at strains that are one-third to one-half the yield strain of intact geomembranes. The method presented in this paper makes it possible to quantify the reduction in HDPE geomembrane yield strain due to scratches as a function of the scratch depth and the geomembrane thickness. Alternatively, the method can be used to select the thickness of an HDPE geomembrane for a given required yield strain when a certain scratch depth is expected.
