An Elegant and Fast Method to Predict the Slow Crack Growth Behaviour of High Density Polyethylene Pipe Materials

摘要

Resistance to slow crack growth is an important material property of polyethylene which determines the application lifetime, especially for utility pipe applications. Usually, the slow crack growth resistance of materials is assed by time consuming testing methods such as NPT, FNCT, PENT, etc. These methods require often the use of notched samples, the use of specific fluids (e.g. detergents) and elevated temperatures.
