Abstract
AbstractThe strain hardening test (SHT) is based on uniaxial tensile testing to estimate the time to failure. It has been shown that the strain hardening modulus can be easily determined using SHT with testing times only a few hours. Due to the same molecular processes during SHT and conventional methods such as full notch creep test (FNCT) and Pennsylvania edge notch test (PENT), the strain hardening modulus covers the slow crack growth (SCG) resistance in pipe‐grade high‐density polyethylene (PE‐HD) to a high degree. The contribution summarizes the results of SHT, carried out on PE‐HD. It discusses the effects of geometry of the test specimens, and the correlation with the PENT and FNCT.
