The applicability of the Pennsylvania Notch Test for a new generation of PE pipe grades
The failure mode termed long time brittle failure (due to slow crack growth ? SCG) limits the lifetime of plastic pipes. There are now two main accelerated tests (PENT and FNCT) that enable us to estimate the lifet...

Charpy tests for preventing rapid crack propagation in PE pipes
Small crack growth (SCG) limits the lifetime of polyethelene pipes. The extra ordinary circumstance can evolve creation of stress raisers that can lead to form a crack and its rapid propagation (RCP). There are two...

Constraint effect on the slow crack growth in polyethylene
is determined by slow crack growth. In this case plastic deformations are localized just around the crack front. Due to this fact linear elastic fracture mechanics can be usedfor description of the stress field ar...
