Strain hardening behavior of HDPE geomembranes

Abstract

The strain hardening behavior is a good measure for the stress cracking resistance of HDPE geomembranes. Influences of the testing parameters temperature and cross head speed on the strain hardening modulus in material testing of PE were quantified. For tests of HDPE geomembranes at 80 °C and 10 mm/min a good correlation with SP-NCTL tests was demonstrated.
