摘要: Developers of polyethylene grades for pressure pipe seek a deeper understanding the resistance these materials to high rate, plane-stress fracture. The Reversed Charpy and ASTM F 2231 “Thin Charpy” test methods are designed index this property, at appropriately rates, quality control material development purposes. This article demonstrates possibility deriving equivalent information from procedure based on tensile drawing tests, via two more basic properties—yield stress strain hardening modulus—which accessible polymer design.
