Time-Temperature Superposition in Mechanical Durability Testing of Polyethylene Geomembranes

CODEN: GTJODJ

Abstract

The mechanical durability of polyethylene geomembranes is considered in this technical note. Polyethylene plastic pipe research has shown that there are universal factors for shifting high-temperature failure (short time) data to low temperatures (long time). Data presented here indicate that these same shift factors may also apply to geomembranes. Crack growth rate studies are proposed as a supplement to the currently used notched constant tensile load tests.
