In this review paper, the influencing factors of the hot⁃ melt welded joints of polyethylene
pipes were briefly described, and the research progress in the reliability testing methods of …

The main aim of the paper is to study the influence of both material inhomogeneity and weld
bead geometry on crack propagation in welded polyolefin pipes. Axially and …

The main purpose of this work was to evaluate the long term performance of butt welded
polyethylene (PE) pipes in comparison to non-welded counterparts. Therefore, old welded …

Purpose–The purpose of this paper is to study the effect of the material inhomogeneity on
crack behavior initiated both axially and circumferentially in or near the butt weld and to …

The paper summarizes our investigations performed with micro-and nanoindentation
techniques and results presented in literature, concerning local mechanical behavior of …

Fracture behaviour of a three-layer polymer pipe subjected to nonhomogenous distribution
of external pressure induced by soil embedding is studied in this paper. Both long term and …

Abstract (DE) Die Kunststoffschweißverfahren Infrarot-und Vibrationsschweißen sind in der
Serienfertigung etablierte Fügetechnologien. Sie sind durch eine wirtschaftliche und …

Electrofusion welding and butt fusion welding are common methods for joining polyethylene
pipes used for water and gas distribution. Because of the wide use of these two methods in …

The purpose of this diploma thesis is to introduce fracture behavior of welded polyolefin
pipes. This study is focused on numerical modelling of the quasi-brittle failure which is a …
