Research Title:
Determination of Waisted Tensile Test Energy-to-Break Factors for Different Pipe Wall Thicknesses
Abstract:

Previous studies showed that tensile test using a waisted specimen is the most discriminating mechanical test for assessing the short term integrity of butt fusion weld in Polyethylene (PE) pipes.

 

Using tensile tests, fracture surfaces of the test specimen should be examined and categorised as either ductile or brittle as tensile strength is a poor discriminator of weld quality.

 

However, this categorization is subjective and qualitative, and degree of ductility reduces significantly will wall thickness.

 

Therefore, in this project the waisted tensile test specimen for qualifying the butt fused plastic pipes will be revisited in order to optimise the test specimen geometry.
